A Butler matrix is a passive beamforming feed network. It is a cost-effective feed network for phased array antennas because the circuit can be fabricated in the form of microstrip lines and is a viable solution for performing beam scanning without deploying expensive active devices. ... Mehr lesen
This model includes a dielectric slab waveguide with a small lossy metallic object nearby. The object causes light to be scattered, absorbed, and both reflected and transmitted along the waveguide. Learn more in this accompanying blog post: Modeling a Scatterer Near an Optical Waveguide Mehr lesen
A bow-tie antenna patterned on a dielectric substrate is optimized by adjusting the length of the arms and the flare angle to reduce the magnitude of S11, reflection coefficient. The two geometric dimensions used as design variables directly control the antenna's size and shape, and also ... Mehr lesen
This tutorial analyzes the hysteresis of the conductance-gate-voltage (G-Vg) curves of an InAs nanowire FET, using the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without a large increase of computational costs. The ... Mehr lesen
This model simulates the velocity of the ionic wind generated by a wire-to-wire corona discharge. Ionic wind, created by the movement of charged particles in an electric field, can be harnessed for various applications, including cooling electronic components and enhancing heat ... Mehr lesen
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Mehr lesen
This tutorial demonstrates how to build the geometry for the 3D biased resonator from GDS file using the ECAD Import Module and the Design Module. The procedure emulates semiconductor and MEMS fabrication processes to build 3D geometry more efficiently and is more intuitive for those ... Mehr lesen
Uncertainty quantification is used to study the effect of manufacturing variation on the performance of a 2D solidly mounted resonator (2D SMR). This tutorial shows how the resonant frequency is affected by thickness variations of the piezoelectric layer and the Bragg reflector layers. ... Mehr lesen
This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift-diffusion model. The model uses the Stabilized Convection-Diffusion Equation interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of ... Mehr lesen
This example shows how to model a FinFET in 3D. The I-V characteristics of the device are simulated. First, the gate voltage is swept to obtain the drain current versus gate voltage plot. Then, the drain current versus drain voltage characteristics are computed for fixed gate voltages. Mehr lesen
