Electromagnetic field tapering using all-dielectric gradient index materials

Electromagnetic field tapering using all-dielectric gradient index materials

The concept of transformation optics (TO) is applied to control the flow of electromagnetic fields between two sections of different dimensions through a tapering device. The broadband performance of the field taper is numerically and experimentally validated. The taper device presents a graded permittivity profile and is fabricated through three-dimensional (3D) polyjet printing technology usi...

Influence of Dielectric Materials on In-vehicle Electromagnetic Fields

Numerical simulations and analytical models have been used to investigate the possible impact of various dielectric components of vehicles on internal electromagnetic field distributions. It is found that, apart from the window glazing, the dielectrics investigated have little impact on the internal field populations and average field levels, although there are localized field differences that ...

Water: Promising Opportunities For Tunable All-dielectric Electromagnetic Metamaterials

We reveal an outstanding potential of water as an inexpensive, abundant and bio-friendly high-refractive-index material for creating tunable all-dielectric photonic structures and metamaterials. Specifically, we demonstrate thermal, mechanical and gravitational tunability of magnetic and electric resonances in a metamaterial consisting of periodically positioned water-filled reservoirs. The pro...
