摘要： Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges.

摘要： Arrangement of resonators in an aperiodic configurations are described, which can be used for electromagnetic cloaking of objects. The overall assembly of resonators, as structures, do not all repeat periodically and at least some of the resonators are spaced such that their phase centers are separated by more than a wavelength. The arrangements can include resonators of several different sizes and/or geometries arranged so that each size or geometry corresponds to a moderate or high “Q” response that resonates within a specific frequency range, and that arrangement within that specific grouping of akin elements is periodic in the overall structure. The relative spacing and arrangement of groupings can be defined by self similarity and origin symmetry.

摘要： Antennas suitable for wideband transmission and reception are disclosed that are useful in environments susceptible to vibration and impact motion such as for example vehicles of various types, e.g., automobiles, trains, etc. The apparatus can include a bicone antenna including two cone-shaped elements. The physical shape of at least one of the two cone-shaped elements may be at least partially defined by one or more pleats (e.g., a series) that extend about a portion of the cone. An antenna can further includes a mast for supporting the bicone as well as a second antenna section including a fractalized dipole. The fractalized dipole can be configured as a conformal circuit board conforming to the shape of the mast and can include self-similar portions or extensions. The antenna may also include a counterpoise to balance the electrically conductive conformal portion. The counterpoise may be defined substantially by a repetitive tooth-like pattern.
