In this letter, the curve linear-linear (CLL) basis functions are extended to higher-order hierarchical linear-linear (HOLL) basis functions. The accuracy of method of moments (MoM) solution for both ...

This paper proposes a basis-function canonical piecewise-linear (BF-CPWL) function, which can approximate any continuous function using a weighted sum of PWL BFs. The BF-CPWL approximation integrates ...
