Resonant Sciences prides itself on its state of the art measurement capabilities and measurement systems and in their responsiveness to customer needs from accuracy, quality, cost and lead time perspectives. Resonant Sciences takes a unique computational electromagnetics analysis/design approach which insures accurate measurements and system design.

Resonant Sciences has designed and fully analyzed multiple free space, guided wave, and resonant cavity measurement systems. These include focused beam systems up through 40 GHz, fully automated radome characterization systems, high temperature free space and guided wave systems, resonant cavity systems, and our our own Electromagnetic Measurement Probe (EMP) antennas and measurement systems. Numerous variants of our EMP systems are currently fielded, including bench-top testing systems, high temperature systems, scanning array systems, among others.

When considered collectively, Resonant Sciences' fielded measurement systems cover multiple polarizations (measuring or calculating TE, TM, CP co- and cross-pol, and Axial Ratio), broad frequency range (measuring 100 MHz - 40 GHz), broad temperature range (measuring ambient – 2400 deg F), broad angles of incidence (measuring broadside to 10 degrees from grazing), broad target dimensions (measuring targets as small as less than an inch to more than 10 feet in length and width), and broad target shapes and compositions (measuring solids, liquids, gasses, composites, layered structures, antennas, scatterers, planar and non-planar, isotropic and anisotropic). Bare bones solutions as well as fully automated systems are available to fit the needs of customer resources.

EMP Antennas

Resonant Sciences' EMP antennas are the basis for a wide variety of our test fixtures. Currently, there are four standard antenna bands that cover 1.5 – 40 GHz. These antennas have small spot size and low VSWR. Other custom bands available upon request.

EMP Benchtop Measurement System

The EMP Benchtop Measurement systems are low and high band capable, compact transmission and reflection measurement systems. These systems fit on laboratory benchtops. and are capable of angle and polarization dependent measurements from 1.5-40 GHz.

EMP Automated Array

Resonant Sciences offers a measurement solution that integrates an array of their electromagnetic microwave probe (EMP) antennas with customized fixturing to permit automated, accurate and rapid characterization of materials and structures. Bandwidth of the system is probe dependent with options including (but not limited to): WRD580 (6-16 GHz), WRD750 (8-18 GHz), WD180 (18 – 40 GHz), (as pictured) WRD350 (3.5 – 8 GHz), WRD150 (1.5 – 5 GHz), as well as standard waveguide bands. The system has fully automated motion and data collection and is material/system qualification worthy.

EMP Array (conveyor variant)

A variant of the EMP automated array is also available from Resonant Sciences. This variant provides all the capability of the EMP automated array, with the added microwave measurement stability associated with a stationary measurement system and a moving part under test.

Sundial System

Resonant Sciences offers a bistatic reflection capable (horizontal) EMP measurement system. This sundial system is capable of +/- 70 degrees in angle, can cover 1.5-40 GHz (in EMP antenna bands), and is TE and TM measurement capable.

SpIDR System

Resonant Sciences offers a Specular Inspection and Diagnostic Ring (SpIDR) measurement system. This system is based on a ring configuration of Resonant Sciences' EMP antennas and is capable of transmission (normal and off normal incidence), normal incidence reflection, and bistatic reflection. This system can measure TE and TM polarization and over broad incidence angles. This system can be configured to operate from 3.5-40 GHz (6-16 GHz band shown). This system is capable of full motion and data collection automation and is material qualification worthy.

SpIDR Sytem (imaging variant)

Resonant Sciences offers a imaging variant of the SPiDR system that is designed for rapid imaging of targets. The system uses broadband (4-40 GHz) antennas and dielectric lenses. Target rotation and data collection are fully automated.

SpIDR Sytem (horizontal variant)

A horizontally oriented variant of our SpIDR system is also available. This system combines the horizontal aspects of the Sundial system with the rail and four antenna concepts of the SpIDR system. The system can operate from 4-40 GHz and test at precise pin-located angles from normal incidence to 60 degrees for both polarizations.

ScIMITar Measurement System

Resonant Sciences offers a Scanning Inspection and Measurement of In-Situ Targets (ScIMITar) measurement system. This system is a monostatic or quasi-monostatic reflection measurement system. System is designed to be a mobile system capable of obtaining monostatic reflection data from various in-situ targets in a laboratory/research environment. The system can be configured to operate from 3.5-40 GHz (18-40 GHz shown) and is capable of a 55 degree adjustment in look angle for either TE or TM measurements. The antenna height from floor and distance from the target are adjustable. The system uses digital angle measurements and can be automated.

RaVIn Measurement Systems

Resonant Sciences offers a variety of Radome Verification and Inspection (RaVIn) measurement systems. The system shown here is capable of transmission/reflection measurements from 4-40 GHz and can be configured for broad angular inspection of TE and TM polarizations. The system is fully automated for motion, data collection, and data processing. The system shown is used for production rate measurements and radome flightworthiness and provides significant time and cost savings for radome inspection.

Focused Beam Systems and Furnace Design

Resonant Sciences custom designs focused beam systems. Both broadband and narrow band (lower VSWR) systems are available. These systems are in use with prime contractors for material and part qualification at room and elevated temperatures. Resonant Sciences has designed and provides custom furnaces as well for a variety of high temperature measurement needs.

Onyx Line of Waveguide Measurement Systems

Resonant Sciences offers low VSWR rectangular and dual ridge waveguides from 150 MHz to 40 GHz. These systems can delivered with high quality positioners.

SQuID Measurement System

Resonant Sciences offers a cavity inspection capability referred to as the System Quality Inspection Device (SQuID) measurement system. The current version is based on a WR1150 waveguide-cavity and provides real time quality control measurements on time dependent targets (e.g., flowing inks, reel-to-reel materials, etc.). The system provides fully automated data monitoring, processing, and collection and is used for monitoring production material quality. The system utilizes a low cost, one-port device.

EMPIRE Software

EMPIRE (Electromagnetic Material Parameter Inversion Routines Executable) is Resonant Sciences' material parameter extraction software product/application. EMPIRE can be provided as an executable (no MatLAB needed). The software has a user friendly interface, built in uncertainty calculator and multiple (expandable) extraction options for free space and guided wave measurements.

Measurement and CEM Services

Resonant Sciences provides measurement service expertise for magnetic and dielectric materials and other EM materials/structures. Resonant Sciences' measurement capabilities include free space (room and elevated temperature), rectangular waveguide, stripline, and cavity (at room and elevated temperature). Custom measurements with other fixtures are possible. Resonant Sciences also offers a wide array of computational electromagnetics modeling and signal processing services.
