Parametrically controlled Tamm states of 1D magnetophotonic crystal in microwaves

The nonpropagating surface modes (surface states) of electromagnetic waves on the interface of 1-D ferrite based magnetophotonic crystal (MPC) adjacent to various opaque media have been studied theoretically and experimentally in the millimetre waveband. These states are direct analogue of non-travelling Tamm surface states in condensed matter physics and correspond to localization of electromagnetic field near the interface. Opaque media are represented with the system of wires (ldquowire mediumrdquo) or another photonic and magnetophotonic crystal in stop-band. The Tamm peak was identified experimentally and its position in the frequency gap of MPC was calculated.
