The Analysis of Thin Wires using Higher-Order Elements and Basis Functions

A method of moments formulation using higher-order wire segments and basis functions for calculating the currents on arbitrarily-shaped wire structures is presented. This approach leverages recent novel advances in techniques for evaluating the integrable singularity. Results indicate that fewer higher-order bases are needed than the usual ten unknowns per wavelength rule of thumb. This approach is expected to be useful in advancing mesh (h-adaptive) and basis function (p-adaptive) algorithms for arbitrarily-shaped wire structures
