Macro Basis Function interactions accelerated with the Inhomogeneous Plane Waves

Abstract

This paper focuses on the direct computation of the interactions between the Macro Basis Functions (MBFs) defined on distinct sub-domains using their complex patterns. They are computed using a set of inhomogeneous plane waves, which can be viewed as an extension of the Fast Inhomogeneous Plane Wave Algorithm (FIPWA), using a new spectral-domain sampling. Examples of slot antennas and 3D frustum array are used to validate the proposed method.
