研究目的
To solve the waveguide port setting problem in FEM calculating, presenting the waveguide port exciting formulation so that the position of waveguide port can be placed anywhere in the calculating domain.
研究成果
The calculational formulations of exciting appointed direction wave for finite element method are presented and validated. The method ensures the sole direction of wave propagation by presenting equivalent sources of electric and magnetic current sources simultaneously.
研究不足
The paper does not explicitly mention limitations, but it implies that previous methods limited waveguide port settings to external surfaces of enclosures, which is addressed by the proposed method.
1：Experimental Design and Method Selection:
The methodology involves presenting calculational formulations for exciting appointed direction waves using the finite element method (FEM). It includes deriving equivalent sources of electric and magnetic current sources to ensure the sole direction of wave propagation.
2：Sample Selection and Data Sources:
