A signal integrity (SI) analysis gives an overview of the quality of an electrical signal transmitted through electrical circuits, such as high-speed interconnects, cables, and printed circuit boards. The quality of the received signal can be distorted by noise from outside the circuit, ... 詳細を見る
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ... 詳細を見る
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
Galvanic corrosion between two different phases (alpha and beta phases) in a metallic (magnesium) alloy is simulated for a representative cross-sectional microstructure configuration. A key feature in the model formulation is the implementation of both anodic and cathodic regions at ... 詳細を見る
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... 詳細を見る
In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube ... 詳細を見る
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... 詳細を見る
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
This example shows an approximate approach to model a dot-in-well solar cell as described by Asahi et al. in the reference paper. The quantum wells and the layers of quantum dots are each treated as lumped energy levels in the band gap. The authors specify transitions between the dot ... 詳細を見る
Extending the High Voltage Insulator model, this example shows how to set up an Optimization Study to determine the optimum position of the grading rings to obtain the highest flashover voltage. 詳細を見る
