Building any device requires the use of materials and in electromagnetism it is often the case that nature does not provide what we need. Hence the concept of a metamaterial which adds the engineering subwavelength structure within a material to the choice of chemical composition. In this way entirely novel properties have been realised most prominent of which have been metamaterials with a...

METAMATERIAL DEVICES BASED ON NANO GAP HYBRID LC MICROCAVITIES
Metamaterials based on split-ring resonators have been the subject of intense research efforts in the last two decades. Initially conceived to manipulate the magnetic response of solids [1], metallic metasurfaces have found applications in sensing [2] as well as in flat optics [3] .Among other features, the metallic split ring...

We propose to use building blocks of THz metamaterials and THz plasmonics for advanced accelerators. Metamaterial building blocks and plasmonic structures allow for a precise control of the electromagnetic near-field distribution in a volume that is defined by the geometry of the structure. THz radiation with wavelengths on the order of a hundred micron is well matched to the transverse and...

Phononic crystals (PCs) and acoustic Acoustic metamaterials (AMMs) are artificially structured composite materials that enable manipulation of the dispersive properties of elastic waves, exploiting Bragg scattering or the presence of localized resonances. Generally, they are periodic distributions of cavities or inclusions (scatterers) embedded in a matrix. Among their unique vibrational...

The heating, current drive and diagnosis of magnetized plasmas relies heavily on the injection and emission of electromagnetic waves. The requirements for beam steering and focusing are stringent and, often, unique. As an example, perfect focusing of Electron Cyclotron Emission requires that higher frequencies be focused at larger distances from the receiver. This implies the need for a...
