In this paper, we designed a EM wave absorber in transparent type at V-band for countermeasure EMC problems. Firstly, we suggested the structure of a transparent-type EM wave absorber consisting of polycarbonate (spacer) which are used for support fixture and two TiO2 films layers (transparent resistive sheets) which are used for reflection and absorption films. Secondly, a design method of the EM...
In this paper, we investigated EM wave absorber for a ceiling of a tollgate in ETC system. The EM wave absorber samples were made of CPE and Flake Sendust powders, which can be manufactured with mechanical forging of spherical Sendust powders using attrition mill to get high value of magnetic permeability and dielectric permittivity in high frequency range. The absorption ability of the samples were...
