SMA connectors are popularly used on printed circuit boards (PCB) for testing. This model shows how to excite an SMA connector on a microwave substrate and how to terminate a grounded coplanar waveguide (GCPW) with 50 ohm using a lumped port and an air-bridge. En savoir plus
Dielectric microspheres can support whispering gallery modes with high optical quality factors. This model illustrates how to compute the different eigenmodes and resonance frequencies. The resonance frequencies are either filtered by their spatial localization in the resonator or by ... En savoir plus
A signal integrity (SI) analysis gives an overview of the quality of an electrical signal transmitted through electrical circuits, such as high-speed interconnects, cables, and printed circuit boards. The quality of the received signal can be distorted by noise from outside the circuit, ... En savoir plus
This tutorial performs steady-state and transient analysis of the response of a PIN diode to constant and pulsed radiation, respectively. The effect of radiation is modeled as spatially uniform generation of electron-hole pairs within the device. At high dose rates the separation of the ... En savoir plus
This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... En savoir plus
It is more difficult to generate laser emissions in the short-wavelength part of the visible and near visible part of the electromagnetic spectrum than in the long-wavelength part. Nonlinear frequency mixing makes it easier to generate new short wavelengths from existing laser ... En savoir plus
This example shows how to use the Optimization Module to find a coil geometry giving a uniform magnetic field on axis and minimal field near the axis ends. En savoir plus
A 180° Ring Hybrid (Rat-Race Coupler) is a four-port network with 180° phase difference between two ports. It is cheaper to manufacture this type of microstrip line component compared to a wave guide 180° hybrid junction, so called magic-T. The objective of this model is to compute the S ...

Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... En savoir plus
