| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, the fabrication of a super thin wave absorber using a dielectric loss material was studied.Firstly, the relative permittivity of the materials was measured by using waveguide-method.It was found that the maximum value was 78.3-j13.8 at 1.8 GHz,and the material had anisotropic characteristics.The material was alternating-stacked to resolve the anisotropic, and the relative permittivity of the sample was calculated and its relative permittivity showed that the value close to arithmetic average.Then, the absorbers with the matching frequency of 2.0 GHz were fabricated alternating-stacked and unidirectionally-stacked samples. As the results, the separation of the matching frequency was more than 200 MHz for the polarized wave direction of the unidirectionally-stacked sample.On the other hand, the alternating-stacked sample had the value of absorption which was more than 20 dB between 1.89 and 1.97 GHz and the separation of only 80 MHz regardless of the polarized wave direction.The fabricated sample thickness was very thin as 4.52 mm. |
