Multiscale modeling is a challenging issue in modern simulation. This occurs when there are vastly different scales in the same model. For example, your cell phone is approximately 10 cm, yet it receives GPS information from satellites 20,000 km away. In these models we examine several ... Mehr lesen
This model demonstrates how to use topology optimization with milling constraints to design a metalens that focuses a single wavelength to a point. This involves transferring the optimized results to another component so the result can be verified using an explicit geometry ... 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
The thermal effects of a laser beam incident on a Semiconductor Saturable Absorber Mirror (SESAM) are simulated under a range of incident beam powers. This is done in two steps. The first study simulates the multiphysics combination of the saturated absorption of the beam on a SESAM, ... Mehr lesen
This model simulates the coupling of free-space laser radiation into waveguide modes using an optical grating coupler. The coupling efficiency and the radiation loss are calculated for different angles of incidence of the laser beam. Mehr lesen
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... Mehr lesen
This proof-of-concept model showcases how to handle a Gaussian beam propagating in the negative y direction in 2D. The model includes several studies, including a parametric sweep, to cover a wide combination of settings describing the background Gaussian beam, such as settings for ... Mehr lesen
This model is based on the Metasurface Beam Deflector model. The performance is improved using shape optimization by allowing both the radii and the position of the individual pillars to change. Mehr lesen
In this model a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular ... Mehr lesen
In this model of a single-beam optical trap, SiO2 nanospheres in streaming water pass by or get captured depending on where they are released from. The electromagnetic force on the particles is calculated in the Electromagnetic Waves, Frequency Domain interface, with a Gaussian ... Mehr lesen
