This model of a circular waveguide demonstrates how to use ports with numerical solution of the port modes. For User definedPolarization, select an Input quantity — Electric field (default value) or Magnetic field — and define the mode field amplitude for the outgoing wave at the port. Read it here. Port phase is disregarded, when using USER DEFINED mode specification, because phase is determined by your mathematical expression. The mode shape will automatically be scaled to unit power before it is used in the port condition. However, if I want to use a 1W TE Note that while COMSOL employees may participate in the discussion forum, COMSOL ® software users who are on-subscription should submit their questions via the Support Center for a In the "Settings" window for the port, under the "Excitation" section, select "User-defined. so , I define ports on wall of the Block domain. Select a Type of port: User defined (the default), Numeric, Circular, Annular, Rectangular, Slit, or User defined (nondispersive). Additional models show how to use impedance and transition boundary conditions to model the conductors, instead of using a These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between volumetric conductors. Learn how to use the Port and Lumped Port boundary conditions in COMSOL Multiphysics for modeling wave electromagnetics problems. 2a. If you click Port Note that while COMSOL employees may participate in the discussion forum, COMSOL ® software users who are on-subscription should submit their questions via the Support Center for a Learn how to copy and reuse boundary mode analysis results in COMSOL Multiphysics® when working with models that have multiple modes of interest. I want to define a 6-port domain in COMSOL 5. Circular and Coaxial ports In the "Settings" window for the port, under the "Excitation" section, select "User-defined. The type of port is "numeric" while there is no definition for the mode. The . It is possible to compute all of the modes of interest using just a single Port boundary condition of type Numeric and to copy and reuse these solutions in all Select the Type of Port — User defined, Numeric, Rectangular, Coaxial, Circular, or Periodic. It illustrates how to align the polarization of This Documentation and the Programs described herein are furnished under the COMSOL Software License Agreement (www. " This will allow you to define the excitation function for the port. Circular and Coaxial ports are available in 3D and 2D axisymmetry. Here I want to do the simulation in 3D model. For both options, enter the Waveguide length L (SI unit: m) modeled with the lumped Select User defined for nonuniform ports, for example, a curved port and enter values or expressions in the fields — Height of lumped port hport (SI unit: m), Width of lumped port wport (SI unit: m), and These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between If the port has a different cross section than either of these, use the User defined option or the Numeric (0,0)-mode port. When specifying the user-defined phase functions, you defined wave 1 to correspond to the transmitted wave. I want to excite port#1 and read the powers arrive to another ports. com/comsol-license-agreement) and may be For User defined, enter user defined expressions for the Mode shape un and the Mode wave number kn. comsol. Learn how to copy and reuse boundary mode analysis results in COMSOL Multiphysics® when working with models that have multiple modes of interest. These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between This article covers how to use lumped ports in electromagnetics modeling in COMSOL Multiphysics®. Depending on the selection, Modeling User Defined Lumped Ports Application ID: 113551 These models demonstrate the usage of the user defined lumped port and lumped elements to If User defined is selected, enter values for the Wave number k, the Specific characteristic acoustic impedance Z. Periodic ports are available in 3D and 2D. Select the Type of Port — User defined, Numeric, Transverse electromagnetic (TEM), Rectangular, Coaxial, Circular, or Periodic. These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between volumetric conductors. Wondering whether you should use uniform, coaxial, multielement uniform, or user-defined lumped ports in your RF models? Here's a guide on Learn how to use the Port and Lumped Port boundary conditions in COMSOL Multiphysics for modeling wave electromagnetics problems. I tried to use "user defined " port. The Plane wave option represents a situation where the boundary layers are not Learn how to copy and reuse boundary mode analysis results in COMSOL Multiphysics® when working with models that have multiple modes of interest. Thus, here specify that there should be no second wave incident at this boundary.
