Fast and efficient analysis of finite large arrrays

Abstract

This thesis presents a fast and efficient analysis of finite large arrays. The Precorrected Fast Fourier Transform (P-FFT) technique, based on the surface integral equations, is employed and developed to largely reduce the memory requirement and computational cost, which makes it possible to analyze very large array problems with full-wave method in personal computers. In this thesis, multilayered planar arrays and waveguide slot arrays are studied using the P-FFT method. Furthermore, full-wave sensitivity analysis with an adjoint technique is also investigated for the optimization in computer aided design (CAD), which is a complement for the fast analysis and makes the fast algorithm studies more complete for both analysis and design.
