Comsol lumped port 2d
WebUse the Lumped Port node to apply a voltage or current excitation of a model or to connect to a circuit. A lumped port is a simplification of the port boundary condition. A Lumped Port condition can only be applied on boundaries that extend between two metallic boundaries — that is, boundaries where Perfect Electric Conductor, Impedance ... WebThe Lumped Port feature connects a waveguide or duct inlet/outlet to a lumped representation element. This can be an Electrical Circuit, a two-port network defined through a transfer matrix, or a lumped representation of a waveguide.Basically, it couples the end of a waveguide to an exterior system that has a given lumped representation. …

WebAll Answers (4) if the waveguide is rectangular, set the port to rectangular and be sure that your frequency range is in where that only the first mode is excited. after simulation you will see ... When modeling electromagnetic structures (e.g., antennas, waveguides, cavities, filters, and transmission lines), we can often limit our analysis to one small part of the entire system. Consider, for example, a coaxial splitter as shown here, which splits the signal from one coaxial cable (coax) equally into two. We know … See more We can begin our discussion of the Lumped Port boundary condition by looking at the fields in a coaxial cable. A coaxial cable is a waveguide composed of an inner and outer conductor with a dielectric in between. … See more To begin discussing the Port boundary condition, let’s examine the fields within a rectangular waveguide. Again, there are analytic solutions for … See more We have introduced the Lumped Port and the Port boundary conditions for modeling boundaries at which an electromagnetic wave can pass without reflection and where we know something about the shape of the fields. … See more
