Electromagnetics Modeling Presentation, General IntroductionElectromagnetics Modeling Presentation, General Introduction

This presentation gives an overview of the electromagnetics modeling capabilities of the COMSOL Multiphysics environment. The focus is on the products AC/DC Module and RF Module. Statics, Low-Frequency and High-Frequency applications...

Plasmonic Wire GratingPlasmonic Wire Grating

A plane wave is incident on a wire grating on a dielectric substrate. Coefficients for refraction, specular reflection, and first order diffraction are all computed as functions of the angle of incidence. The model is set up for one...

RF HeatingRF Heating

This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block...

Microwave OvenMicrowave Oven

This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency domain electromagnetic analysis followed. This is followed by a transient heat transfer simulation showing how...

Computing the Radar Cross Section of a Perfectly Conducting SphereComputing the Radar Cross Section of a Perfectly Conducting Sphere

A classic benchmark problem in computational electromagnetics is to solve for the radar cross section (RCS) of a sphere in free space illuminated by a plane wave. This model solves for the RCS of a metallic sphere that has a very high...

Second Harmonic Generation of a Gaussian BeamSecond Harmonic Generation of a Gaussian Beam

Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are an even multiple of the frequency of the laser light. This model shows how a second harmonic...

Microstrip Patch AntennaMicrostrip Patch Antenna

The microstrip patch antenna is used in a wide range of applications since it is easy to design and fabricate. The antenna is attractive due to its low-profile conformal design, relatively low cost and very narrow bandwidth. It is...

Optical Scattering off of a Gold NanosphereOptical Scattering off of a Gold Nanosphere

This model demonstrates the calculation of the scattering of a plane wave of light off of a gold nanosphere. The scattering is computed for the optical frequency range, over which gold can be modeled as a material with negative...

Radar Cross SectionRadar Cross Section

This tutorial model demonstrates the use of a background field in an electromagnetic scattering problem. Although this example is a boat hit by a radar, this same technique can be used in any situation where an isolated object meets...

Balanced Patch Antenna for 6 GHzBalanced Patch Antenna for 6 GHz

Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques....
