Abstract
In one embodiment, an electromagnetic (EM) energy containment device includes a spherically symmetric resonant dielectric structure having a radial dimension R0 defined as R0=3/π·λ0/2 and having first and second regions with different indices of refraction. The spherically symmetric resonant dielectric structure is configured to receive and to contain, for a selectable duration of time, an electromagnetic wave of a wavelength λ0, and can find applications in delay circuits for beam steering for example.
