Cavity Resonance Absorbers

Cavity Resonance Absorber product series is a thin magnetically loaded sheet stock having loss at microwave frequencies, while maintaining the desirable characteristics of elastomeric binders.

Cavity Resonance Absorbers are designed to exhibit high loss and are intended to be applied to metal surfaces inside microwave cavities to reduce the Q of the cavity.

Cavity Resonance Absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 GHz to 20 GHz.

  • Magnetically loaded sheet stock
  • High loss at microwave frequencies
  • Application on metal surfaces inside to reduce the Q of the cavity
  • Attenuation of energy at normal and high angles of incidence at frequencies from 1 GHz to 20 GHz
