Analyzing Time-Domain Reflectometry for 2 Electrical Designs

October 23, 2017

Here are 2 examples of analyzing the signal integrity and time domain reflectometry in electrical devices: a high-speed interconnect and a set of parallel microstrip lines.

Simulating Extraordinary Optical Transmission at Terahertz Frequencies

October 20, 2017

One potential approach to improving medical imaging, quality assurance, and other terahertz applications is extraordinary optical transmission, a process that can be studied with RF simulation.

Analyzing Kelvin Probe Designs with COMSOL Multiphysics®

October 4, 2017

Kelvin probes, a type of MEMS technology, provide a nondestructive and contact-free way to measure the work function differences of various material combinations.

Improving IFE Target Fabrication with a Droplet Microfluidics Method

September 29, 2017

A common joke is that fusion energy is 30 years away, and always will be. Researchers are using simulation to tackle the challenges involved with of inertial fusion energy target production.

Analyze the Electrodynamics of a Magnetic Power Switch via Simulation

September 21, 2017

The AC/DC Module can be used to simulate electrodynamic devices, such as magnetic power switch circuit breakers. Follow along with this discussion to study the working principles of the device.

Silicon Photonics: Designing and Prototyping Silicon Waveguides

September 19, 2017

John Tyndall tried to control the most visible form of energy, light, using 2 buckets and some water. Today, there is a more advanced device for this purpose: a silicon waveguide.

Optimizing the Geometry of Optical Antennas with Genetic Algorithms

September 12, 2017

What does antenna design have to do with the concept of natural selection? Although it may sound far-fetched, the basic principles of natural selection can be used to optimize antenna geometries.

Learning Quantum Mechanics Concepts with Double-Barrier Structures

August 30, 2017

Quantum mechanics is a notoriously difficult subject to learn — and teach. Modeling a double-barrier structure is an effective way to teach quantum mechanics concepts to physics students.
