The parameters of pulses reflected from non-periodic Bragg layered structures have been investigated. The specific structures such as asymmetric resonators with periodic Bragg reflectors and structures with chirp variation of the thickness of the “period” have been examined. The numerical investigations have been made both in Bragg band and outside it. The frequency characteristics of the structures...
The problem of selection of convenient model of wideband frequency response of open resonance structures was examined. Importance of influence of the quasi-resonance effects on formation of resonance curve is demonstrated. For quasi-resonance accounting the square root singularity was used.
As frequency-selective devices for millimeter and submillimeter waves, open resonators are widely used. Selective properties of open resonators are defined by their frequency response. In many cases it is convenient to use model for representation of the frequency response of the open resonator. For example, utilization of model considerably simplifies search of complex natural frequencies of the...
