RF Signal Transformation Between the Time and Frequency Domains

September 25, 2018

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

September 13, 2018

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

September 10, 2018

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

August 14, 2018

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

August 9, 2018

Using the Semiconductor Module, you can study the program and erase cycles of an electrically erasable programmable read-only memory (EEPROM) device.

Investigating a Three-Port Ferrite Circulator Design with RF Simulation

July 13, 2018

Get a quick introduction to microwave circulators and modeling them with the RF Module. The featured example is a three-port ferrite circulator.

Optimizing ISFET Designs with Multiphysics Simulation

July 2, 2018

Ion-sensitive field-effect transistors (ISFETs) measure pH levels for soil analysis, the production of dairy products, and more. Multiphysics simulation can help us optimize these devices.

The Nonparaxial Gaussian Beam Formula for Simulating Wave Optics

June 26, 2018
