This tutorial model is of a micro perforated plate (also known as MPP) backed by a vibrating structure. This is a typical configuration in, for example, a MEMS microphone. The vibrating structure is not modeled explicitly, but just assigned a vibration velocity. The vibrating structure ... Mehr lesen
Graphene, carbon atoms arranged in a two-dimensional hexagonal lattice has sparked tremendous research and application interests since its experimental discovery about two decades ago. Besides being ultrathin, this magical material exhibits a plethora of interesting properties, ... Mehr lesen
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 ... Mehr lesen
Multipaction can occur when electrons are accelerated by a high frequency RF field into surfaces. At certain frequencies, the number of electrons in a cavity can grow exponentially. This exponential growth cannot continue indefinitely because space charge effects in the cavity can ... Mehr lesen
The capability to alter the polarization of light is crucial to a wide variety of optical devices. For example, the polarization of light has a significant effect on the performance of optical isolators, attenuators, and beam splitters. By assigning a specific polarization to light, most ...

A plane-wave mode feeds an axisymmetric horn radiating from an infinite baffle toward an open half space. The radius of the waveguide attached to the horn throat is assumed to be fixed, as well as the depth of the horn and the size of the horn mouth attached to the baffle. By varying the ... Mehr lesen
This example simulates the separation of particles based on the size in a microchannel using the method of pinched flow fractionation. The microdevice has two inlets and multiple outlets where the velocity field of liquid flow is calculated using the Laminar Flow interface. Then the ... Mehr lesen
Recent advances in the fabrication of microfluidic systems require handling of live cells and other micro particles as well as mixing. All this can, for example, be achieved using acoustic radiation forces and the viscous drag from the streaming flow. Streaming: Due to the nonlinear ... Mehr lesen
This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface. The exterior acoustics are modeled using the Pressure ... Mehr lesen
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Mehr lesen
