Development of the Malyuzhinets Method for Wave Tracing Modeling at Right-Angled Areas

Ray-tracing simulation of electromagnetic millimeter-wave propagation in an in-building or urban environment for radio channel characterization requires modeling plane wave diffraction by various objects. Such objects can be simulated using opaque impedance or semitransparent boundary conditions. This letter finds an exact solution to electromagnetic wave diffraction by orthogonal planes. Generalized semitransparent or opaque impedance boundary conditions characterize these planes. The exact solution is represented by the Malyuzhinets solution for plane and surface wave diffraction by orthogonal opaque impedance planes. We demonstrate that the exact solution contains only geometrical optics fields while an incident wave is a plane one.
