Abstract
The results of numerical modeling the transmission coefficient of multilayer band filter in THz frequency range are given. The filter structure contains two metal diaphragms of the cross-wise shape. Nanocomposite material is located between these two conductive surfaces. It is possible to change dielectric properties of nanocomposite material by the choice of a concentration and dimensions of nano-particles in the matrix. Effective permittivity was calculated using the models of Cole-Cole and Davidson-Cole. The filter proposed in the present paper is able to provide the relative frequency band of 6% by the level of −3 dB at the frequency of 0.14 THz. Insertion loss of the filter are not more than 5 dB. The developed device is intended to operation over the millimeter-wave range and can be used in the circuits of telecommunication, radiolocation and medicine equipment.
