Distribution of electromagnetic waves of a microwave range to periodic comb structures
In introduction an object of investigation is pointed - the periodic comb structure consisting of cermet plates on the basis titanate of calcium and aluminate lanthanum of the round form, disposed definitely is indicated. The purpose of research is distribution of electromagnetic waves of a microwave range to periodic comb structures. In the main part the technique of realization experiment on research mechanism of distribution and localization of electromagnetic waves of a microwave range in periodic comb structures is in detail opened. It is described two cases of a relative positioning of elements in the investigated periodic comb structures placed in the microwave range a field. Researches were conducted in frequency band 7,5-8,5 GHz. In the first case experimental researches of a relation of a power spectrum of passing of structure from the lattice period are conducted. In the second case experimental researches of a relation of a power spectrum of passing are conducted at certain value of a step and distances between the central plates. The arrangement that at a certain relative positioning of elements in investigated periodic comb structures, on determinate frequency, the structure shows good spectral selectivity. There is an attenuation of a signal more than on 70 dB. Results of an experimental research of laws of distribution and localization of electromagnetic waves of a microwave range in periodic comb structures. Results of measurements are presented in the form of charts. On the basis of results of researches, it has been assumed that at a certain arrangement of elements in the investigated periodic edge structures, the given structures can be used for designing of new components of the microwave range electronics: filters, interferometers and etc.
