High Performances of X-Band Wave Absorber for TE and TM Polarizations using Transparent Resistive Film

An X-band transparent wave absorber for TE and TM wave polarizations is examined theoretically and experimentally. In the case of both polarizations, the absorption of 20dB or more was obtained at the frequency ranging from 8.5 to 11.5 GHz, and the incident angle between 0 and 40 degrees under the target frequency of 10 GHz and the target incident angel of 20 degrees. The optical transmittivities of the presented wave absorber of about 80% or more was also obtained, as expected.
