Abstract

A ferrite fin electromagnetic wave absorber is developed for a glass curtain wall. The ferrite fin absorber has been studied as a component structure of the ferrite grid absorber. Structure of the absorber is designed by calculation with transmission line method for oblique incidence. The characteristics are measured using mock-ups for the glass curtain wall with the time domain method. The developed absorber suppresses reflection below -17 dB in the frequency range between 80-800 MHz for incident angle, of 60°. The absorber can be applied to the TV ghost problem in both of VHF and UHF bands
