Abstract

An analysis of electromagnetic scattering by multi-story, multi-window buildings is presented by utilizing the Kirchhoff Approximation method. This investigation specifically analyzes scattering characteristics for vertically polarized incident plane waves. Scattering fields are calculated via radiation integrals associated with equivalent current sources induced on the building's exterior and across virtually closed window apertures by the incident wave. Fields within window regions are represented using rectangular waveguide modes, enabling the conversion of reflected fields from window glass into equivalent currents. The formulation's validity is established through comparisons with the physical optics method and scale model measurements. Discussions address the influence of window glass and polarization on wave propagation in wireless communication scenarios like 4G LTE operating at 700 MHz.
