Acceleration of Finite Periodic Structures Analysis Through Full-Domain Basis for Matrix Compression

Approaching large finite periodic structures with the surface integral equation-method of moments (SIE-MoM) framework is a challenging kind of problems in terms of memory and computing time. Slotting the MoM matrix with slotFFT techniques has proven to be an efficient approach to reduce both metrics through the application of FFT. In this work we propose the integration of a matrix compression method with a controlled impact on the precision based on full-domain distributed basis to improve the acceleration given by the slotFFT method.
