Modal Composition of the SiC Surface Electromagnetic Response to the External Radiation at Lattice Resonant Frequency
To observe the direction of the surface polariton wave excited by the external radiation on the semi-infinite crystal surface, the opaque mask was placed onto the sample surface. The penetration of the surface polariton wave from the open surface in beneath the metal mask was observed via small openings in the mask. It was shown that despite the k-vector mismatch between the surface polariton states and the light in the environmental media (vacuum), non-zero efficiency of the surface wave excitation is still present and that the k-vector of the excited wave corresponds to the k-vector projection of the driving light.
