This model studies the dispersion of neutral species band through curved microchannel in an Electroosmotic flow (EOF) . Using Optimization module, geometric optimization is carried out to minimize the curve-induced dispersion.The central idea is to parametrically represent the geometry ... En savoir plus
It is possible to realize a narrowband bandpass filter using cascaded microstrip coupled lines. In this example, a design composed of cascaded microstrip lines, each approximately a half wave length in size at the resonant frequency, is analyzed. The model is solved for the S-parameters ...

Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... En savoir plus
A classic benchmark problem in computational electromagnetics is to solve for the radar cross section (RCS) of a sphere in free space illuminated by a plane wave. This model solves for the RCS of a metallic sphere that has a very high conductivity, which can be treated as a material with ... En savoir plus
An anechoic chamber is used to measure antenna characterization, electromagnetic interference (EMI), and electromagnetic compatibility (EMC). Within the chamber are absorbers that are configured with an array of pyramidal objects that steer the propagating incident field onto their ... En savoir plus
The shape of a log-periodic antenna resembles that of a Yagi-Uda antenna, but is composed of a coplanar array to achieve a wider bandwidth. It is also known as a wideband or frequency-independent antenna. All metallic parts are modeled using the perfect electric conductor (PEC) boundary ... En savoir plus
This example simulates electroplating of a printed circuit board (PCB) in 3D using the Secondary Current Distribution interface. In order to achieve thickness uniformity across the PCB, a dummy pattern is included in the design, along with an aperture in the electroplating bath. En savoir plus
This tutorial utilizes the Particle Beam feature to examine the performance of a high-precision spectrometer. An ion beam is subjected to electric and magnetic forces, and only a fraction of the incoming beam is transmitted to the detector. The Particle Counter feature is used to compute ... En savoir plus
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. En savoir plus
While transient analyses are useful for time domain reflectometry (TDR) to handle signal integrity (SI) problems, many RF and microwave examples are addressed using frequency domain simulations generating S-parameters. However, from the frequency domain data it is difficult to identify ... En savoir plus
