This Application Gallery entry demonstrates how Far-Field radiation can be calculated when a substrate is present. Two approaches are demonstrated. A simplified form that works for two homogeneous domains, and a general approach that can handle multiple, inhomogeneous layers. This ... Mehr lesen
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ... Mehr lesen
Solarkonzentrator-/ Cavity-Receiver-Systeme können dazu verwendet werden, die einfallende Sonnenstrahlung auf einen kleinen Bereich zu fokussieren und intensive Wärme zu erzeugen, die dann in elektrische oder chemische Energie umgewandelt werden kann. Eine gängige Kennzahl für ... Mehr lesen
This tutorial model shows how to model a microspeaker located in a smart phone including the radiation through and interaction with the acoustic port that connects to the exterior. The model demonstrates a linear frequency domain analysis as well as a nonlinear time domain analysis. A ... Mehr lesen
A cascaded cavity filter provides much better bandpass filter performance compared to a single cavity. Out-of-band rejection improves dramatically using a cascaded design. This model uses three rectangular cavity filters coupled via slots. The calculated S-parameters show excellent out ... Mehr lesen
An acousto-optic modulator (AOM) is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, that is, the modification of the refractive index by the oscillating ... Mehr lesen
One way to generate circular polarization from a microstrip patch antenna is to truncate the patch radiator. This model is tuned around the GPS frequency range. The axial ratios are calculated to show the degree of circular polarization. Mehr lesen
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... Mehr lesen
This example simulates the propagation of a positive streamer in transformer oil under a lightning impulse voltage. The space charge density and the electric field are obtained. The simulated streamer radius agrees well with the measured values. Mehr lesen
One way to design a filter is to use the element values of well-known filter prototypes, such as maximally flat or equal-ripple low-pass filters. It is easier to fabricate a distributed element filter on a microwave substrate than a lumped element filter, since it is cumbersome to find ... Mehr lesen
