Focusing a laser beam onto the tip of a single mode fiber is a common way to couple light. To achieve good coupling efficiency, the spatial mode of the light field has to match the spatial mode of the fiber. In this model, we use the beam envelopes method to compute a small free-space ... 詳細を見る

In its simplest form, an optical ring resonator consists of a straight waveguide and a ring waveguide. The waveguides are placed close to each other, making the light affect each between the two structures. If the propagation length around the ring is an integral number of wavelengths, ... 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

This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. 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

This tutorial model solves for a hydrogen plasma created in a microwave cavity. The model computes the fluid flow and gas heating self-consistently. 詳細を見る

This model analyzes an RF MEMS switch consisting of a thin micromechanical bridge suspended over a dielectric layer. A DC voltage greater than the pull-in voltage is applied across the switch, causing the bridge to collapse onto the dielectric layer with a resulting increase in the ... 詳細を見る

Compact camera modules are widely used in electronic devices such as mobile phones and tablet computers. In order to reduce both the size and number of elements required the optical design will typically incorporate several highly aspheric surfaces. This model demonstrates a five element ... 詳細を見る

This tutorial shows how to set up a multi-element objective lens. The chosen lens is a Petzval lens with field flattener described in 'Fundamental Optical Design', by M. Kidger, 2001, pg 192. The tutorial demonstrates how to include a geometric sequence using the 'Spherical General Lens ... 詳細を見る
