Interference heat emission in an absorbing layer in the presence of a two-wave field

The control of the interference heat emission upon the oblique incidence of two counterpropagating (with respect to the transverse component of the wavevector) identically linearly polarized coherent waves on the opposite sides of an absorbing layer is considered. The dependences of the interference heat emission on the angle of incidence and the layer thickness are established for various refractive indices and absorption coefficients in weakly and strongly absorbing media. The conditions for the maximum interference heat emission are determined.
