EMI Shielding, S-Parameters & mmWave Characterization

RF, microwave, and mmWave material characterization for shielding effectiveness, absorption, reflection, transmission, dielectric behavior, and S-parameters. Elect Nano uses this capability as part of application-driven materials programs where test setup, sample format, and data interpretation need to match the end-use requirement.
