In this paper, coupled field analysis methods in finite element analysis software are investigated. 3D mechanical modeling software Solidworks 2011 and general finite element analysis software ANSYS Workbench 14.0 are used in combination, and two sets of sequential coupling simulation schemes containing thermal-vibration sequential coupling analysis and vibration-thermal sequential coupling analysis...
A modified tri-mode stepped impedance resonator (SIR) is proposed, in which a shunt open stub is loaded in the conventional tri-section SIR. The resonant frequencies and frequency ratios can be properly controlled by adjusting the loaded open stub. A compact second-order tri-band bandpass filter (BPF) based on two coupled proposed open stub loaded tri-section SIR...
Arrayed wave guides coupling is the frontier of the current opt electronic technology. In this paper, the arrayed coupling between wave guides and optical fiber were studied, including the coupling efficiency and the 1dB tolerance. Finally, it can be obtained the influencing rule of the mode field mismatch loss and the misalignment loss on the coupling efficiency.
This paper provides the design and realization of high frequency circuit simulator (HFCS) which is based on the finite element method. For vilification, the cold-test characteristics of two actual helical slow wave structures have been calculated and the results were found to be consistent with those of HFSS simulation with same mesh density.
