The frequency selective surfaces (FSS) find application in many diverse area, such as polarizers, antenna reflectors due to their resonance properties. In the case of infinite FSS are used: mode — matching method [1] and spectral — domain approach [2],[3]. For the infinite 20 periodical arrays is convenient to use the Floquet harmonics for the field representation in the free space.
The parameter energy link loss between the source of the transmitter and the load of the receiver is used to evaluate the performance of a ultrawideband (UWB) radio system. The rigorous calculation of the link loss in a UWB system requires a complicated full transient solution for the transmit and receive antennas. However, after involving suitable approximations, the optimization problem is converted...
