Efield® Waveguide Modesolver
The waveguide modesolver is used to compute waveguide eigrnmodes used by the Efield® time domain (EfieldTD) solvers or the Efield® frequency domain (EfieldFD) solvers for waveguide and antenna applications. It is also used as absorbing boundary conditions for RCS simulation of perfectly matched antennas or RCS simulation of large open-ended cavities such as air-intakes.The Efield® waveguide modesolver can handle
- TE, TM and TEM modes for general shaped homogeneous ports
- Analytical for rectangular, circular and coaxial ports
- Hybrid modes for general shaped inhomogeneous ports
- Modes used as ABC’s in an RCS simulation
RCS of geometries with cavities
The Efield® waveguide modesolver is used in a tool for computing the radar cross-section (RCS) of geometries with large open-ended cavities. The problem is decomposed into an exterior and an interior problem, the cavity, which are treated independently of each other.
