RF Modeling in COMSOL Multiphysics®

August 16–19, 2022 11:00 a.m. EDT

Back to Events Calendar

This 4-day online training course will cover the modeling of antennas, waveguides, transmission lines, microwave circuits, cavities, filters, and metamaterials using COMSOL Multiphysics® and the RF Module. After 2 days of class, there will be a 1-day gap where trainees will work on assigned exercises and explore the features in the software relating to their own application areas.

Depending on the interests of the attendees and time permitting, the following topics will be addressed:

  • Different types of excitation, such as plane, dipole, and cylindrical waves
  • Using Port conditions to excite waveguide structures
  • Evaluating scattering parameters
  • Plotting E-field propagation for different phases without recomputing the model
  • Features such as the Perfect Electric Conductor (PEC), Perfect Magnetic Conductor (PMC), Impedance boundary condition (IBC), Transition boundary condition (TBC), and Perfectly Matched Layers (PMLs)
  • Modeling time-domain reflectometry and signal integrity analysis
  • Applications such as coaxial cables and RF waveguides
  • Evaluating the resonant frequency and quality factor of closed- and open-cavity structures by solving the eigenvalue problem
  • Applications such as microwave cavities, optical resonators, and coil resonance structures
  • Approaches for modeling passive devices, RF or microwave couplers, and filters
  • Combining resonant structures and transmission lines
  • Quantifying the electric and magnetic field distribution, impedance, and S-parameters
  • Using the Impedance boundary condition to take into account the skin effect at a very high frequency
  • Using PMLs to truncate the modeling domains effectively
  • Geometry and meshing techniques needed while considering PMLs
  • Quantifying far-field patterns, losses, gain, directivity, impedance, and S-parameters
  • Applications such as microstrip patch, Vivaldi, and dipole antennas
  • How background electromagnetic fields of known shape, such as plane waves, interact with various materials and structures
  • Quantifying the scattering cross section, absorption cross section, and the associated losses
  • How to visualize the total fields and scattered fields
  • Performing analysis of a single unit cell with Floquet periodic boundary conditions
  • Application areas including frequency-selective surfaces, optical gratings, and electromagnetic band-gap structures
  • Modeling capability of the full time-dependent wave equation
  • Quantifying losses and how they lead to the rise in temperature over time
  • Setting up bidirectional couplings between electromagnetic and thermal models
  • Application areas including thermal drift in a cavity filter, microwave ovens, absorbed radiation in living tissue, tumor ablation, effects of deformation on the modes of propagation, and stress-optical effects
