The shape of a log-periodic antenna resembles that of a Yagi-Uda antenna, but is composed of a coplanar array to achieve a wider bandwidth. It is also known as a wideband or frequency-independent antenna. All metallic parts are modeled using the perfect electric conductor (PEC) boundary ... Mehr lesen
This model studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. Mehr lesen
Modern cars have rear-windshield FM antennas to play FM radio. The radiation emitted from an antenna induces an electric current on the outer surface of any cable harnesses in the car, which can have negative effects. This model uses the RF Module to compute the far-field radiation ... Mehr lesen
A tapered slot antenna, also known as a Vivaldi antenna, is useful for wide band applications. Here, an exponential function is used for the taper profile. The objective of this model is to compute the far-field pattern and to compute the impedance of the structure. Good matching is ... Mehr lesen
Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. Mehr lesen
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... Mehr lesen
This app demonstrates the following: Multiple components (1D and 3D) in a single app Using the same choice list in the app as in the model using Data Access functionality Output numerical results for a specific time step using a combo box The app combines the Ray Optics Module and ... Mehr lesen
This model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. Mehr lesen
Antenna crosstalk, or co-site interference, is problematic when multiple antennas are used on a single large platform. In this model, the interference between two identical antennas at VHF frequency is studied with an S-parameter analysis of different configurations of a receiving ... Mehr lesen
The Yagi–Uda antenna is designed for a specific Wi-Fi band and can reduce eavesdropping by directing signals with the help of directors. This antenna consists of one uniformly spaced reflector and four directors. Simulated results show a maximum 10 dBi gain and a front-to-back ratio of ... Mehr lesen
