TL;DR: In this article, a finite-element EM-based simulators and space-mapping optimization are combined to produce an accurate design for manifold-coupled output multiplexers with dielectric resonator (DR) loaded raters.

TL;DR: In this article, it was shown that a modulated Gaussian beam undergoes negative refraction at the interface between a positive and negative refractive index material, and the interference fronts appear to bend in a manner suggesting positive refraction, such that the true direction of the energy flow associated with the refracted beam is not obvious.

TL;DR: Though transformation optical media are generally anisotropic, with both electric and magnetic response, it is possible to arrive at a dielectric-only transformation optical distribution for a lens interacting with transverse-magnetic (TM) polarized light.

TL;DR: In this article, a gradient index (GRIN) lens using a negative index of refraction material (NIM) has been designed and tested using an electromagnetic code to design the required ring and wire unit cells.

TL;DR: This work predicts and experimentally achieves a complete suppression of the resonance amplitude using an 815 nm laser source and briefly considers the problem of tuning the frequency of an SRR by the same method.
