A new global finite element analysis of microwave circuits including lumped elements

Fast MRI coil analysis based on 3-D electromagnetic and RF circuit co-simulation

“…One of the most significant developments in field solver technologies is the creation of a two-way link between RF circuit and 3-D EM simulation tools [7,8]. This enables simulation results from the RF circuit domain to be used to drive the 3-D EM domain.…”

Full-wave modeling and automatic equivalent-circuit generation of millimeter-wave planar and multilayer structures

“…Full-wave analysis methods used for the modeling of distributed parts have to be combined with lumped subcircuits. One possible way is to directly integrate lumped elements into a full-wave analysis [1]- [3], but it is advantageous to separate EM and network simulation combining the single simulation results afterwards [4]. This procedure reduces the modeling effort and increase efficiency.…”

New Formulation of the Iterative Method: Application to a Microwaves Attenuator

“…To avoid these useless steps consisting in simulating low-size elements, a solution resides in the introduction of the localised elements "lumped element" [1] into the electromagnetic software: finite elements [2], finished differences [3]. Another more rigorous solution consists in simulating the various parts of the circuit by adequate methods and equalizing the fields in extreme cases of the fields [4].…”
