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 ... 詳細を見る
When modeling the propagation of charged particle beams at high currents, the space charge force generated by the beam significantly affects the trajectories of the charged particles. Perturbations to these trajectories, in turn, affect the space charge distribution. The Charged ... 詳細を見る
Large lithium-ion batteries are widely deployed in electric vehicles and for stationary energy storage applications. In the (stacked) pouch battery cell design, all current exits the cell on the cell "tabs", and as the cell size and power increase, the voltage gradients in the highly ... 詳細を見る
This model compares the results of five different formulations and approaches to solving an RF heating problem consisting of a coaxial cable inserted into a sample of lossy dielectric material. Results show that the different formulations agree over a wide frequency band. To learn more ... 詳細を見る
FEM simulation can be used to obtain a SAW velocity and some related parameters (squared electromechanical coupling coefficient, reflectivity, etc.) for different typical configurations. Such parameters are input data for various analytical and semi-analytical methods of SAW device ... 詳細を見る
This model shows how to include the nonlinear (large signal) behavior of certain lumped components in a simplified loudspeaker analysis. The mechanical and electrical system is modeled using an equivalent electrical circuit. The large signal compliance CMS(x) and force factor BL(x) are ... 詳細を見る
This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). Microconnector bumps are used in various types of electronic applications for interconnecting components, for instance liquid crystal ... 詳細を見る
This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... 詳細を見る
The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The tail and head mass lower the resonance ... 詳細を見る
This is a model of the Brüel and Kjær 4134 condenser microphone. The geometry and material parameters are those of the actual microphone. The modeled sensitivity level is compared to measurements performed on an actual microphone and shows good agreement. The membrane deformation, ... 詳細を見る
