Summary :

We present a realization of the transparent wave absorber effective for the use at V-band frequency. First, we propose a structure of the transparent wave absorber consisting of spacer (polycarbonate) and two transparent resistive sheet (polyethylene terephtalate deposited with Indium Tin Oxide) used as a reflection film and an absorption film. Second, a design chart for this type of wave absorber is shown. Third, a design method and manufacturing process of the transparent wave absorber are described particularly for V-band frequency. As a result, the measurement of reflection loss of the absorber indicate that a peak absorption of 32-38 dB is attained at a target frequency of 60 GHz.
