Artificial dielectrics are fabricated electromagnetic materials consisting of synthetic substances, usually constructed in an orderly arrangement, such as arrays. The arranged materials, and the distances between them are usually evenly spaced on, or within, a substrate. Hence, the arrays of inclusions are in a periodic or lattice structure. Also, the lattice spacing is smaller than the impinging electromagnetic wavelength. These were first conceptualized, constructed and deployed for interaction in the microwave frequency range in the 1940s and 1950s. The constructed medium, the artificial dielectric, has an effective permittivity and effective permeability, as intended.

A device for thermal treatment of gases and pollutants employs alternate cavity (1) and susceptor (9) geometries for providing more homogeneous interactions of applied electromagnetic energy (6) in the volume of the susceptor (9) regardless of the flow rate and diameter of the exhaust duct (3) width. The heat transfer methods improve the overall heat efficiency of the device. The susceptor (9) structure has reflectivity as principle mode of interaction with applied electromagnetic energy (6) which allows for energy to penetrate the susceptor (9) which is formed of composite susceptive materials. The use of field concentrators (5) to concentrate the energy density of the applied electromagnetic energy (6) provides a simple method of controlling the temperature versus energy in the susceptor (9).

Slotted antenna including an artificial dielectric substrate with embedded periodic conducting rings, for achieving an ideally-uniform, hemispherical radiation/reception when used as a single antenna element, or for azimuth(φ)-independent impedance-matched electronic beam scanning when used as a large antenna array
A new antenna includes a rectangular slot element provided on a conducting plate and covered by a special substrate portion. The substrate portion includes stacked layers of capacitively-loaded conducting ring elements, arranged in the form of an (e.g., periodic) array in each layer. The slot antenna element is excited by a parallel-plate waveguide, which is fabricated below the conducting plate on which the slot antenna is made. The antenna design, when used in the form of a single antenna element, would produce ideally uniform power radiation over all directions in the upper hemi-spherical space. A large periodic array of such ideally isotropic antenna elements permits electronic beam scanning and has a performance of power coupling from signal sources at the antenna inputs which is independent of the azimuth (Φ) scanning direction, dependent only on one spatial variable (elevation angle, θ) of scanning. Such performance from an antenna array normally can not be achieved using conventional designs. Such an antenna array may be used in communications and radars.
