Lightning Surge Analysis of an Offshore Wind Farm

This model analyzes lightning surges in an offshore wind farm. When a lightning strike with a current of 20 kA hit one wind turbine, the induced electric fields in adjacent wind turbines were computed. 詳細を見る

Circularly Polarized Antenna for GPS Applications

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. 詳細を見る

Modeling of a Grounded CPW Using Numeric TEM Ports

This tutorial example shows how to set port features in a physics interface when designing a grounded coplanar waveguide (GCPW) circuit that is useful for mmWave applications. 詳細を見る

Modeling a Biconical Antenna for EMI/EMC Testing

Biconical antennas are popular for very high frequency (VHF) measurement because they support a wide frequency range. They are also useful for electromagnetic compatibility (EMC) testing where the antenna can be used as an RF source in susceptibility or immunity test. This model ... 詳細を見る

Radome with Double-Layered Dielectric Lens

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 ... 詳細を見る

FEM–BEM Coupling of a Microstrip Patch Antenna

This tutorial model analysis of a microstrip patch antenna shows how to couple the finite element method (FEM) to the boundary element method (BEM) for evaluating the field outside the FEM computational domain. The model computes the S-parameter, near-field distribution, and far-field ... 詳細を見る

Waveguide Iris Bandpass Filter

A conductive diaphragm, an iris, placed transverse to a waveguide aperture causes a discontinuity and generates shunt reactance. Bandpass frequency response can be achieved from cascaded cavity resonators combined with these reactive elements which can be created by inserting a series of ... 詳細を見る

Evanescent Mode Cylindrical Cavity Filter

An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... 詳細を見る

Designing a Waveguide Diplexer for the 5G Mobile Network

A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... 詳細を見る

Interpolating Material Data on a Regular Shape as an Alternative to Building an Irregular Geometry

Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... 詳細を見る
