“…This approach employs a new expression for the gradient of the thin wire kernel derived from a recent technique for numerically evaluating the exact thin wire kernel. This approach should provide essentially arbitrary accuracy and may be used with higher-order elements and basis functions using the procedure described in [4]. …”

“…The subsections are represented by quadratic parametric transformation to accurately model the curvilinear surfaces. It was well analyzed that the parametric quadratic triangular element modeling has the advantages in accuracy, convergence, and computation time than using linear triangular elements [11][12][13]. The MOM with pulse basis functions and point matching in conjunction with the quadratic triangular element is simple, accurate, and faster convergence.…”

In this article, free space capacitance of dielectric-coated conducting curvilinear surfaces is obtained using method of moments (MOM). The surfaces are discretized using triangular subsections. The curvilinear surfaces are represented by quadratic parametric elements. The MOM based on the pulse basis function and point matching is used. The integrand is divided into a regular and a singular part. The regular part of the integral is numerically evaluated by using the Gaussian quadrature algorithm for triangles. The Duffy transformation is used to evaluate the singular part of the integrals. Computed results are given for the capacitance of the dielectric-coated conducting cylinder of finite axial length and truncated cone, and compared with the previously published results.

“…For example, Czawka and Garbaruk [12] offer a design framework to control the radiation pattern from a multiport antenna by using a lossless multiport to control phase of the feeds. A fast and generalized antenna code is critical to the optimization of such an antenna system [7]. Figure 32 illustrates such a system optimization and blurs the distinction between the matching circuit and the antenna.…”
