[EN] An enhanced full-wave method based on circuit analysis is presented in this paper, where the whole set of modes TEmnp and TMmnp are taken into account. The modeling of a split cylinder resonator is done with two circuit ...
Penaranda-Foix, Felipe L.; Janezic, Michael D.; Catalá Civera, José Manuel; Canós Marín, Antoni Josep(Institute of Electrical and Electronics Engineers (IEEE), 2012-09)
In this paper, a full-wave method for the electromagnetic analysis of dielectric-loaded cylindrical and coaxial waveguides and cavities is developed. For this purpose, a new four-port ring network is proposed, and the ...
