A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares the results to the Fresnel equations. Mehr lesen
The transmission speed of optical waveguides is superior to microwave waveguides, because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. This model is an example of a single step-index waveguide made of silica glass. The inner ... Mehr lesen
Frequency-selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. Mehr lesen
This model analyzes lightning surges in an offshore wind farm. When a lightning strike with a current of 20 kA hit one wind turbine, the induced electric fields in adjacent wind turbines were computed. Mehr lesen
Scientists use the SAR (specific absorption rate) to determine the amount of radiation that human tissue absorbs. This measurement is especially important for mobile telephones, which radiate close to the brain. The model studies how a human head absorbs a radiated wave from an antenna ... Mehr lesen
Developments in the last decade have made circuit quantum electrodynamics (cQED) the leading architecture for quantum computation. cQED is the solid-state version of cavity QED, which studies the basic light-matter interactions at the quantum level. This model examines one of the main ... Mehr lesen
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... Mehr lesen
This example model calculates the bistatic radar cross section (RCS) per unit length of a circle using the Electromagnetic Waves, Time Explicit physics interface. A 2D circle is excited by a 200 MHz sinusoidal signal modulated by a temporal Gaussian pulse. A wideband RCS frequency ... Mehr lesen
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 conductivity, which can be treated as a material with ... Mehr lesen
