This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... Mehr lesen
Dieses Modell verwendet das Wave Optics Module und das Ray Optics Module, um die Ausbreitung von Strahlen durch ein Beugungsgitter bei verschiedenen Einfallswinkeln zu modellieren. Es verwendet die S-Parameter, die mit dem Interface Electromagnetic Waves, Frequency Domain auf einer ... Mehr lesen
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... Mehr lesen
This is an example of a Fabry-Perot cavity, the simplest optical resonator structure. It is a classical problem in optics and photonics. Two methods are shown for computing the Q-factor. The losses in this model are purely via radiation away from the resonator. Mehr lesen
A Czerny-Turner monochromator spatially separates polychromatic light into a series of monochromatic rays. This model simulates a crossed Czerny-Turner configuration that consists of a spherical collimating mirror, a planar diffraction grating, a spherical imaging mirror, and an array ... Mehr lesen
Optical lenses of millimeter size cannot easily be analyzed with the Electromagnetic Waves, Frequency Domain interface on standard workstations due to the large number of finite element mesh elements required. This model explains how the Electromagnetic Waves, Beam Envelopes interface ... Mehr lesen
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... Mehr lesen
The Schmidt-Cassegrain Telescope demonstrated in this tutorial is a classic design using an aspheric corrector lens and two spherical mirrors. The aspheric corrector is created using the 'Aspheric Even Lens 3D' part from the Ray Optics part library. Mehr lesen
A Luneburg lens is a type of graded index, or GRIN lens, in which the gradient of the refractive index leads to special focusing properties. This example model uses the Geometrical Optics interface to compute the curved ray trajectories in the graded-index medium. Mehr lesen
A corner cube retroreflector can be used to reflect rays in a direction exactly antiparallel to their initial direction, regardless of the angle of incidence. This tutorial shows how to simulate the reflection of a bundle of rays at a corner cube retroreflector using the Geometrical ... Mehr lesen
