WebMar 7, 2011 · A non-overlapping and non-conformal domain decomposition method (DDM) is presented for modeling large finite antenna arrays. Two major benefits of the proposed DDM: (a) A mixed true second order transmission condition (SOTC) with corner edge penalty terms is developed to facilitate fast convergence in the DDM iterations. …
WebThe mesh periodicity reinforces the array’s periodicity. Quantitatively, a direct solver with 12 computing cores took just more than five hours and 60.8 GB RAM to optimize the spacing for an 8 x 8 antenna array, while a finite array DDM with 12 computing cores required just 45 minutes and 1.8 GB RAM for the same solution.
