The toroidal dipole is a localized electromagnetic excitation, distinct from the magnetic and electric dipoles. While the electric dipole can be understood as a pair of opposite charges and the ...
Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash The theory could have broad ranging applications ...
A new project by researchers at the University of California San Diego will investigate a biological mystery that has so far gone unsolved: can organisms use radio frequencies to sense surroundings?
Fig. 1 The dielectric response models for conventional dielectric materials and for metamaterials. For conventional dielectric materials, there are three types of polarization models: Drude model for ...
