This example demonstrates how to plot the interference pattern from the combination of two rays with slightly different optical path length. A simple Michelson interferometer is used to achieve a change of optical path length by slightly moving one of the mirrors. En savoir plus
Electron transport in low-temperature plasmas depends strongly on the electron energy distribution function (EEDF), which is often approximated as Maxwellian but is frequently nonequilibrium in reality. Incorporating nonequilibrium EEDF behavior into spatially dependent models often ... En savoir plus
A Butler matrix is a passive beamforming feed network. It is a cost-effective feed network for phased array antennas because the circuit can be fabricated in the form of microstrip lines and is a viable solution for performing beam scanning without deploying expensive active devices. ...

This model compares the results of five different formulations and approaches to solving an RF heating problem consisting of a coaxial cable inserted into a sample of lossy dielectric material. Results show that the different formulations agree over a wide frequency band. To learn more ... En savoir plus
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... En savoir plus
A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... En savoir plus
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ...

HowTo: Using the EC External I-Terminal The External Couplings in the CIR interface has two flavors that can be used. External I vs. U and External I-terminal. The former has two nodes (it represents a differential external voltage measurement) and when coupling to an EC Terminal ... En savoir plus
This is a transient model of an electromagnetic plunger consisting of a magnetic core, nonmagnetic guider, multi-turn coil, and magnetic plunger attached to the spring and damper at the far end. The electromagnetic force on the plunger due to the transient current in the coil is ... En savoir plus
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... En savoir plus
