Abstract
Two-phase crystal-like structures for the resonance and band filtration of signals are proposed. It is shown that the selectivity of a two-phase resonator is higher than that of a traditional half-wave one. Implementation of band filtration by coupled resonators is considered. Experimental and calculated characteristics of a band filter on the basis of a two-phase electromagnetic crystal are presented.
