研究目的
To investigate the efficiency and flexibility of combining the body-of-revolution and finite element methods for full-wave analysis of waveguides and waveguide discontinuities involving angular field variation.
研究成果
The combination of body-of-revolution and finite element methods significantly improves the efficiency of discrete analysis for axially symmetrical guiding structures, reducing computational time by up to two orders of magnitude. This technique is comparable to analytical approaches in flexibility and efficiency, making it useful for the design and optimization process of waveguides and waveguide discontinuities.
研究不足
The approach may require a significant number of modes for complex geometries, potentially leading to numerically ill-conditioned scattering matrices. The method's efficiency is highly dependent on the structure's geometry and the discretization quality.
