MR1: Tuned Frequency Absorbers

MAST Technologies’ Tuned Frequency Absorber product series is a thin magnetically loaded sheet stock. Tuned Frequency Absorbers, also known as resonant frequency absorbers, provide great reflection loss at a discrete frequency, typically offering 20dB of attenuation. Tuned Frequency Absorbers offer a narrowband of absorption, typically +/-10% of the resonant frequency, so are best used when a single discrete frequency is trying to be absorbed. MAST Engineers can tune an absorber to any frequency from 1 to 40 GHz, by simply changing the formulation and thickness.

Typical Applications

  • Ship masts
  • Specular return (RCS)
  • Discrete frequency absorption
  • Antenna isolation and patterning
  • Aircraft seals
  • Aircraft ducts
  • Instrument housings
