Self-Consistent Schrödinger-Poisson Results for a Nanowire Benchmark
This benchmark model of a GaAs nanowire validates the Schrödinger-Poisson Equation multiphysics interface, which is useful for modeling systems with quantum-confined charge carriers.
How to Use Numeric Ports in Your RF Analyses
When performing RF analyses in the COMSOL® software, you can use numeric ports to compute the mode of a port with an arbitrary shape. This demonstration includes a waveguide adapter example.
RF Signal Transformation Between the Time and Frequency Domains
Want to make your RF and microwave device modeling more efficient? Read this blog post to learn how to implement the fast Fourier transform in your simulations.
Optimizing the Performance of a Dielectric Resonator Antenna
Dielectric resonator antennas (DRAs) have a storied history that began in the 1800s. Today, they are used in satellite, radio, and nanophotonics, and even show potential in 5G communications.
Evaluating a Schottky Diode with a Semiconductor Benchmark Model
We present a model of a Schottky diode with benchmarked results, validating the use of simulation to analyze the performance of semiconductor devices.
Calculating the Spectral Properties of an Optical Ring Resonator
The effect of a “whispering gallery” can be observed (a similar way) in another field of science entirely: light waves traveling in an optical ring resonator.
Studying the Program and Erase Cycle of an EEPROM Device
Using the Semiconductor Module, you can study the program and erase cycles of an electrically erasable programmable read-only memory (EEPROM) device.
