Capacitance in a Microstrip

To illustrate how to calculate lumped parameters of capacitance, this model calculates such in a microstrip. The example shows the two different ways of calculating this: with a static analysis and with a time-harmonic analysis.

Ion Funnel

An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, allowing mixtures of ionized gases to be separated and analyzed while minimizing losses. This model ...

Two-port Piezoelectric SAW Device

This tutorial shows how to model surface acoustic waves in time domain. The 3D modeling geometry represents a 128 degree YX-cut lithium niobate substrate. The SAW device has two ports. The metallic electrodes are modeled as perfect conductors using boundary conditions. The geometric dimensions such as size of substrate, the gap between the ports and the number of inter-digitated electrodes (IDTs) ...

Lumped Receiver Connected to Test Set-up with an 0.4-cc Coupler - new

In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube inlet. The response at the measurement microphone in the coupler as well as the electric input impedance to the ...
