ANTI-WAVEGUIDE PROPAGATION IN A HETEROGENEOUS LAYER,
Abstract
This paper examines the field of a point radiator in a heterogeneous layer in which there is no shear elasticity and the parameter of the medium is a linear function, given H/lambda >> 1, where H is the thickness of the layer, and lambda, the wavelength. It studies theoretically three types of anti-waveguide propagation not formed by total reflection of the boundary surface. A beam interpretation is obtained in the Wentzel-Kramers-Brillouin approximation for the dispersion equation for normal waves. A formula is given for the field intensity in the effective shadow when the boundary condition is described by the numerical coefficient of reflection. (Author)
