| Abstract(in English) | In the millimeter-wave parallel beam method using a dielectric lens, a change due to the in-plane anisotropy of the permittivity appears in the transmission S21 parameter when the sheet material is rotated around the beam axis. Also, by tilting the incident angle, a change due to thickness direction anisotropy appears. In a sheet material whose complex permittivity can be approximated as 1, we investigated and experimentally evaluated a method to estimate the six independent tensor elements of the principal-axis-transformed complex permittivity tensor by measuring the transmission S21 parameters by changing the in-plane rotation angle and the incidence angle, and evaluated the results by comparing them with the measured values. |
