Precise & Cost-Effective Non-Destructive Testing of Critical Materials

Users and developers of non-metallic composite materials need to understand fully their material’s uniformity and isotropy. To do so requires the ability to scan for material defects by measuring the interaction of the material (dielectric properties and magnetic properties) with RF, either over a broad range of frequency or within a specific narrow frequency band of interest.

MWI Laboratories provide a range of Gaussian Beam Reflection Loss Arch systems that utilize MWI’s polyrod antennas. The antennas can be moved independently to permit an angle of reflection from +/-5 degrees to +/-80 degrees.

When used with the MWI PRA_0716 antennas, the systems provide a frequency range of 0.7-16 GHz with a beam size of 12.5 inches diameter at 2 GHz. They can be adjusted for aligning the E-field for Transverse Electric (TE) or Transverse Magnetic (TM) polarities. The systems can accommodate a variety of sample size, the MWI_Arch48, for example, offers a sample test region of 48”x48”x86”.

MWI Laboratories’ Gaussian Beam Polyrod antennas provide a planar wave within 1 inch of the tip and produce a collimating beam (without a focal point) to inspect composite materials.

Similar to a laser, MWI’s collimating RF beam is very directional, narrow and prevents over-illumination of the sample. This makes it very easy for the user to determine where the energy is located in performing non-destructive testing for material characterization, uniformity and defect detection measurements over a wide range of bi-static measurement angles.

The systems are light-weight and easy to operate without the need for an RF engineer. Mechanical and software noise reduction improvements increase dynamic range greater than 70dB while reducing signal scattering and sample wrap-a-round.

Gaussian Beam Reflection Loss Arch Systems

When combined with a Keysight Vector/Performance Network Analyzer the Reflection Loss Arch allows the customer to save time on testing, reduces manpower cost, while increasing product quality if inspected in a Laboratory Quality Assurance (QA) or during manufacturing via an in-process Quality Control (QC) environment.

Customers who have implemented MWI’s Non-Destructive Testing solutions have eliminated the need to machine samples and have reduced scrap rates by as much as 60%, as well as reduced production down time by 85%.
