The Analysis of Thin Wires Using Higher Order Elements and Basis Functions

A method of moments procedure for accurately resolving the currents on arbitrarily-shaped wire structures using higher order basis functions and higher order (curved) wire segments is presented. An advanced integration scheme for straight wires is modified for use on higher order wire segments. The results demonstrate that fewer higher order bases than the usual ten per wavelength may be used. This approach is expected to facilitate efforts to create algorithms for mesh (h-adaptive) and basis function (p-adaptive) adaptive schemes for arbitrarily-shaped wire structures
