Abstract
Lenses and reflectors are common devices in manipulating electromagnetic (EM) wave propagation and are largely utilized in radiation and receiving systems of electromagnetic engineering. The recently proposed significant concept of transformation electromagnetics provided an effective tool to design devices that could control the EM wave with desired ray traces. In this presentation, we will demonstrate several examples of applying the transformation electromagnetics in the design of a novel EM wave lens that could focus EM wave with better resolution than the Abbe-Rayleigh diffraction limit and a planar retrodirective reflector. The design procedures, device performances as well as the consideration of practical realizations will be analyzed.
