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 ...

A waveguide filter is designed using shape optimization. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. Mehr lesen
This model shows how to compute the AC characteristics of a MOSFET. Both the output conductance and the transconductance are computed as a function of the drain current. Mehr lesen
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... Mehr lesen
MEMS scanning mirrors are a type of MEMS device that realizes optical path control by controlling mirror torsion through a microdriver. The torsion can be single axis or double axis. MEMS scanning mirrors are widely used in laser projection, laser radar, laser processing, and other ... Mehr lesen
UHF RFID tags are widely used for identifying and tracking animals. This model simulates a passive radio-frequency identification (RFID) tag for the UHF frequency range. With respect to the chip transponder’s complex impedance, a reflection coefficient is computed. This is done using an ... Mehr lesen
This example demonstrates how to plot the interference pattern from the combination of two rays with slightly different optical path length. A simple Michelson interferometer is used to achieve a change of optical path length by slightly moving one of the mirrors. Mehr lesen
Mixed-mode S-parameters describe the responses of a circuit with balanced ports excited and terminated by two types of modes: common and differential modes. They are calculated using a full S-parameter matrix of a four-port network that is composed of four single ended lines. This ... Mehr lesen
A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths. Mehr lesen
The ball grid array (BGA) technology is a surface-mount technology widely used in electronic packaging. Usually, there are two types of solder balls considered in the array, including the functional balls that are required for electric connections and the support balls that are used only ...
