Una solución híbrida UTD-PO para el análisis de la difracción múltiple de una serie de cilindros asumiendo incidencia de onda esférica

Abstract

A new hybrid uniform theory of diffraction-physical optics (UTD-PO) formulation for the analysis of the multiple diffraction caused by an array of cylinders, assuming sphericalwave incidence, is hereby presented. The solution, validated with numerical data from technical literature, is mathematically less complex and computationally more efficient −for a large number of cylinders− than other existing methods, due to the fact that high-order diffraction terms (slope diffraction) are not considered, without such lack of terms barely entailing any loss in accuracy. Results can be applied in radiowave propagation analysis when multiple diffraction over rounded obstacles has to be considered.
