Mie scattering (DGTD)

Calculate scattering and absorption cross sections, local field enhancements and far field scattering distributions from a nano particle excited by a planewave (mie scattering). The cross section and farfield results are compared with the analytic solution to validate the accuracy of the simulation. Overview Understand the simulation workflow and key Więcej…

Diffraction grating (DGTD)

Characterize a diffraction grating in response to a broadband planewave at normal incidence. Lumerical provides a set of grating scripts for the DGTD solver, making it easy to calculate common results such as number of grating orders, diffraction angles and grating efficiencies at different wavelengths. Overview Understand the simulation workflow Więcej…

Nanobeam grating

This example demonstrates how to use the DGTD to compute the diffraction efficiency and deflection angles of a periodic grating consisting of an array of sub-wavelength silicon beams on top of a glass substrate. As explained in the referenced article, this type of grating is used to steer a beam Więcej…
