Overview The antenna reciprocity theorem [1] relates the antenna load current for given plane wave excitation to the radiation pattern when the antenna is excited. The antenna is assumed to be made of linear and reciprocal components. With the CADFEKO Reciprocal Excitation solution configuration, the antenna load response…
Rotman Lens is a two dimensional, wide-angle microwave lens capable of steering a beam through the use of input ports being individually excited. The number of input ports determine the resolution of the steerability of the beam, and the angle of the outermost ports determines the full angle of the steerability. A white…
This article discusses the parameter tuning of a PSIM Level 2 switch model using a SPICE model as a reference. As you may already know, PSIM offers a wide variety of switch types. Check out the following article about different switch model options before reviewing this one. Learning how to navigate through the PSIM switch…
Connecting HyperStudy with HyperSpice & LTspice using a PSIM schematic PSIM gives three different solver options with PSIM (default), Altair's HyperSpice, and then a link to LTspice. You can use our design of experiments and automation tool, HyperStudy, to run automated simulations with any of these solvers. That being…
White paper "Analysis and Optimization of an Automotive Cradle using Single Finite Element model with Multiple Attributes i.e. NVH, Strength and Fatigue" Finite element analysis has been an important part of vehicle product design. Currently in the industry multiple models of same components/assemblies are built to perform…
