Accurate determination of modes in dielectric-loaded cylindrical cavities using a one-dimensional finite element method

Model-Reduction Method for Electromagnetic Problems

“…The structure is analyzed using the proposed technique and the resonant frequencies are evaluated. Table IV gives the accuracy comparison of the proposed technique with the conventional FEMFD approach and the results reported in [21]. The results match accurately.…”

“…3. This was also studied in [21] chosen to demonstrate the accuracy and CPU speed-up of the proposed method. The finite element mesh consisted of 3432 tetrahedrons with 4531 edges and 3412 unknowns.…”

A one-step leapfrog HIE-FDTD method for rotationally symmetric structures

“…Here e5 e q e / e z ½ T and h5 h q h / h z ½ T are the auxiliary variables which are introduced to speed up the computational efficiency of the proposed method. 15,19 Expanding Equation 6-9, the updating equation for each field component can be obtained. For example, the equations for the auxiliary variables can be written as follows 11 1 j / 2 ði11=2Þ…”

Finite element analysis for complex permittivity measurement of a dielectric plate and its application to inverse problem

“…The modes of a field having no variation in the azimuthal direction have been analyzed based on the scalar FEM [1215], while those of a field having a periodical variation in the azimuthal direction have been analyzed based on the vector FEM with the penalty function method [16,17] and with hybrid edge/nodal elements [1820]. The modes of a field having no variation in the azimuthal direction have been analyzed based on the scalar FEM [1215], while those of a field having a periodical variation in the azimuthal direction have been analyzed based on the vector FEM with the penalty function method [16,17] and with hybrid edge/nodal elements [1820].…”
