Abstract

An integral equation solver is presented using the nested equivalence principle algorithm (NEPAL), which has previously been applied to 2D problems. NEPAL is extended to three dimensions. The algorithm is based on Huygens' equivalence principle by nesting small algorithms within a larger one. The computation is divided into several stages and the number of unknowns at each stage reduced. This represents an efficient algorithm for directly solving the integral equation of scattering with reduced computational complexity of O(N2). Hence, it can be used to compute the scattering solution of large objects for many incident waves.
