Devices have been proposed for two-dimensional (2D) wave propagation of transverse magnetic waves that use special coordinate transformations combined with eikonal-limit approximations (that is, neglecting the impedance gradient) that allow elimination of the out-of-plane magnetic response, and thus ...
The possible EMI shielding mechanism is that when EM waves are incident on the surface of shielding materials, a part of waves are immediately reflected on the interface between air and the film due to their impedance mismatch. Subsequently, another part of EM waves undergoes repetitive reflection...
A hallmark of the quantum Hall effect, and a consequence of nontrivial topology of the electronic properties of systems manifesting this phenomenon, is the existence of so-called chiral edge states. These are a class of unique electronic states through w
The phenomena by which energy in the form of electromagnetic waves emanates from a source into space. 2. Energy transferred through space in the form of electromagnetic waves. NOTE— By extension, the term “electromagnetic radiation” sometimes also covers induction phenomena. (IEC 60050(161)–...
and Sheng Xi. Research in applied transformation based electromagnetics The interactions of electromagnetic wave with a general class of spherical cloaks based on a full wave Mie scattering model is establish analytically. We show that for an ideal cloak the total scattering cross section is absolutely...
