Computer-aided design-based high-frequency electromagnetic wave scattering from complex bodies
… solid modelled bodies and bodies modelled with triangular patch surface elements allows the scattering analysis of arbitrary bodies which can be constructed using CAD packages. The scattering analyses are applied to radar cross section (RCS) problems, cavity radiation problems, and antenna …

Extensions to OpenGL for CAGD.
… OpenGL, emphasize modeling with rectangular patches, which are especially useful in Computer Aided Geomeric Design (CAGD). However, not all shapes are rectangular; some are triangular or more complex. This paper extends the OpenGL library to support the modeling of triangular patches, Coons …

Modified Sierpinski Fractal Antenna
… modifications of the original Sierpinski fractal patch antenna, providing additional parameters to optimize in order to get the required radiation characteristics. A systematic study of the original Sierpinski monopole was done to gain an insight on the operation and multi-band behavior of the …

Multimode and Multiband Microstrip Antennas
… broadband and multiband matching of microstrip patch antennas. Microstrip patch antennas suffer from many constraints on their performance. One major restriction is their narrow impedance bandwidth. An effective method to resolve this is adding more resonators to the antenna structure to achieve …

A Study of Techniques to Solve the Disparate Mesh Size Problem With an Application to Sinuous Antennas
… antenna. The essence of the problem is that a triangular patch mesh containing a wide range in patch sizes produces an ill-conditioned method of moments impedance matrix. Since the FMM algorithm relies on iterative solvers to solve the matrix equation, the fast in FMM becomes a misnomer if the …
