The present work is devoted to the generalisation of operator approach for the solving electromagnetic waves diffraction problems by periodic systems of discontinuities (such transverse slot) in hybrid metal-dielectric structures. The diffraction problem solution of single eigenwave of the hybrid metal-dielectric structure by bounded periodical slot sequences in the metal has been presented. The approach based on the using of semi-infinite periodical structures conception. On the first stage the reflection and propagation coefficients of single slot was found. On the second stage the reflection and propagation coefficients of the semi-infinite sequences of identical discontinuities was found. On the third stage the electrodynamical characteristics of the bounded sequence of identical slot discontinuities was found. By the numerical simulation the dependencies 11 S and 12 S of the structure with single slot and bounded sequences arranged equidistantly was founded. The pattern characteristics are presented.
The electromagnetic waves diffraction by bounded and semi-infinite sequences of plane screens with slot
(Видавництво Національного університету "Львівська політехніка", 2009) Kaliberda, M. E.; Pogarsky, S. A.; Phenichnaya, S. V.
The diffraction problem of electromagnetic waves by the systems of plane screens with slot was considered. The operator approach was used. The possibility of eigenwaves propagation between screens was took into consideration. The dependencies of reflection and transmission coefficients of structure and excitation coefficient of plane waveguides from the distance between screens were investigated.
