Open publisher page 0 citations

Abstract

A time domain(TD) solution based on uniform theory of diffraction-physical optics(UTD-PO) is presented to analyze the multiple-cylinder diffraction.Since the solution utilizes a simple recursion relation,the complicated slope diffraction in UTD is avoided,which provides an improved TD-UTD solution for multiple diffraction.The numerical results show that the improved TD-UTD solution can not only be applied to analyze the multiple-cylinder diffraction for UWB signals,but also significantly reduce the computational time.
