This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... En savoir plus
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... En savoir plus
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. En savoir plus
The electric shielding boundary condition is meant to approximate a thin layer of highly conductive material that provides an additional current path tangential to a boundary. This example compares the electric shielding boundary condition to a full-fidelity model and discusses the range ... En savoir plus
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ...

This model simulates the coupling of free-space laser radiation into waveguide modes using an optical grating coupler. The coupling efficiency and the radiation loss are calculated for different angles of incidence of the laser beam. En savoir plus
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... En savoir plus
This is a model of a simple Sagnac interferometer consisting of two mirrors and a beam splitter arranged in a triangle. The entire modeling domain rotates; as a result, the rays propagating in opposite directions in the triangle have different optical path lengths due to the Sagnac ... En savoir plus
This app demonstrates the following: Parameterized geometries Visualizing material appearance, color, and texture Multiple plots in the same window to visualize the results Options to visualize the results with different views using check boxes Microstrip patch antenna arrays are ... En savoir plus
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 ... En savoir plus
