Oct 01, 2019 · Controlling the propagation of optical fields in three dimensions using arrays of discrete dielectric scatterers is an active area of research. These arrays can create optical elements with functionalities unrealizable in conventional optics. Here, we present an inverse design method based on the inverse Mie scattering problem for producing three-dimensional … 7 Nov 2019 Electromagnetic fields (EMF) produced by electrical and electronic (E&E) can have adverse effects on human health.
