Join us for a 5-day online training course to advance your skills in RF and wave optics modeling.

Day 1: Modeling Resonant Structures, Waveguides, and Transmission Lines

10:30 a.m.–12 p.m. EDT

Setting Up Models with the RF Module: In this session, you will learn how to set up mathematical models of devices such as antennas, waveguides, filters, circuits, cavities, and metamaterials using the RF Module. You will also learn how to have different types of excitation, such as plane wave, dipole wave, and cylindrical wave, as well as how to use the Port condition to excite a waveguide structure and evaluate the scattering parameters and plot the E field propagation for different phases without recomputing the model.

1–3 p.m. EDT

Modeling Waveguide and Transmission Lines: You will learn approaches for modeling RF waveguide and transmission lines, including how to use propagation constants, impedance, and S-parameters to characterize these devices. You will also learn about the time-harmonic transmission line equation for the electric potential for electromagnetic wave propagation along one-dimensional transmission lines, as well as an approach for modeling time domain reflectometry and signal integrity analysis. The application area covers coaxial cable and RF waveguide.

Modeling Resonant Structures: You will also learn how to model resonant structures. We will evaluate the resonant frequency and quality factor of closed- and open-cavity structures by solving the eigenvalue problem. We will discuss applications such as microwave cavities, optical resonators, and coil resonance structures.

Day 2: Modeling Passive Devices, Couplers, Filters, and Antennas

10 a.m.–10:30 a.m. EDT

Q&A

10:30 a.m.–12 p.m. EDT

Modeling Passive Devices, Couplers, and Filters: In this session, you will learn approaches for modeling passive devices, RF/microwave couplers, and filters as well as combining resonant structures and transmission lines. We will also discuss how to quantify the electric and magnetic field distribution, impedance, and S-parameters. The application area involves 3-dB couplers, power dividers, and band-pass filters.

1–3 p.m. EDT

Modeling Antennas and Other Radiating Systems: In this session, you will learn the process for modeling transmitting and/or receiving radiated electromagnetic energy devices. We will demonstrate the use of the Impedance boundary condition for taking into account the skin effect at a very high frequency and efficiently modeling different types of antennas. We will also introduce the use of perfectly matched layers (PMLs) in order to truncate the modeling domains effectively. We will discuss various geometry and meshing techniques needed while considering PML. You will learn how to quantify far-field patterns, losses, gain, directivity, impedance, and S-parameters. Application areas include microstrip patch antennas, Vivaldi antennas, and dipole antennas.

Day 3: Modeling RCS Using Scattering Analysis and Periodic Structures

10 a.m.–10:30 a.m. EDT

Q&A

10:30 a.m.–12 p.m. EDT

Scattering Analysis: In this session, we will discuss how the background electromagnetic field of known shape, such as a plane wave, interacts with various materials and structures. We will showcase how to quantify the scattering cross section, absorption cross section, and the associated losses. You will also learn how to visualize the total fields and scattered fields. Major applications involve Mie scattering and radar cross section (RCS) calculations.

1–3 p.m. EDT

Modeling Periodic Structures: In this session, you will learn approaches for modeling periodic structures that repeat in one, two, or all three directions, as well as how to perform an analysis of a single unit cell with Floquet periodic boundary conditions. Applications include frequency selective surfaces, optical gratings, and electromagnetic band gap structures

Day 4: Modeling Dispersive Materials and Multiphysics Analysis

10 a.m.–10:30 a.m. EDT

Q&A

10:30 a.m.–12 p.m. EDT

Dispersive and Frequency-Dependent Materials: In this session, you will learn an approach for modeling harmonics via a transient wave simulation using nonlinear material properties. We will showcase the modeling capability of full time-dependent wave equation in dispersive media such as plasmas and semiconductors. You will also learn an approach for modeling a linear material model describable by a sum of Drude–Lorentz resonant terms.

1–3 p.m. EDT

Modeling Multiphysics Electromagnetics Analysis: In this session, you will learn how an electromagnetic wave interacts with any loss materials. We will observe how the losses lead to the rise in temperature over time. We will showcase the approach to perform bidirectionally couplings with the thermal equation with any losses computed from solving the electromagnetic problem. Application areas include 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.
