This example demonstrates a simulation setup for exciting surface plasmon polaritons using Otto and Kretschmann configurations. The underlying mechanism is enabled by the interplay between total internal reflection and evanescent-wave coupling phenomena. It also calculates the ... 詳細を見る
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... 詳細を見る
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... 詳細を見る
Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... 詳細を見る
This tutorial model solves for a one-dimensional capacitively coupled plasma reactor in a mixture of argon/oxygen. Important aspects and strategies for modeling electronegative discharges are discussed. 詳細を見る
An acoustic point source emits a pressure wave in water that travels toward a piece of glass. Cracks are formed and propagate due to high tensile stresses developed in the glass. A fully coupled acoustic-structure interaction problem including phase field damage in solids is solved in ... 詳細を見る
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... 詳細を見る
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... 詳細を見る
In the diffuse double layer and within the first few nanometers of an electrode surface, the assumption of electroneutrality is not valid due to charge separation. Typically, the diffuse double layer may be of interest when modeling very thin layers of electrolyte including those in ... 詳細を見る
Ferroelectric materials exhibit nonlinear polarization behavior such as hysteresis and saturation at large applied electric fields. Many piezoelectric materials are ferroelectric. This model analyzes a simple actuator made of PZT piezoelectric ceramic material, which is subjected to ... 詳細を見る
