Abstract: An electromagnetic shield includes a plate-shaped base and first projecting portions. The base has a first surface and a second surface, the first surface being configured to allow an electromagnetic wave to be incident on the first surface. The second surface is distant from the first surface and extends along the first surface. The electromagnetic shield includes a dielectric. In the electromagnetic shield, at least one of the first projecting portions has a side including a first point and a second point, the side makes different inclination angles with a projecting direction of the first projecting portion at the first point and the second point. In the projecting direction of the first projecting portion, the second point is closer to the first surface-than the first point is. On the side, an inclination angle β is greater than an inclination angle α.

Abstract: Provided is a wave control medium capable of controlling waves while decreasing the size of a metamaterial or the like and increasing the bandwidth of the metamaterial or the like.
A wave control medium 10 is formed by combining at least two among a coil 11 and a coil 12 which are three-dimensional microstructures formed into a spiral structure, the coil 11 and the coil 12 including any one of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, or a material selected from a plurality of combinations of these materials, and having functions of a capacitor and an inductor. The coil 11 and the coil 12 form a capacitor between the lateral face of the coil 11 and the lateral face of the coil 12 facing each other, and form an inductor by forming a three-dimensional multiple resonance structure by the coil 11 and the coil 12 having a spiral structure.

Abstract: An array device composed of individual multifrequency passive resonators which are not electrically connected to one another. These resonators are formed by interrupted transmission lines that close back in on themselves and which are nested within one another, each formed of a group of two or more parallel tracks, and are paired with one another contactlessly around one or more dielectric layers of a substrate. Such an array is used in particular to modify an incident magnetic or electromagnetic field, and/or to carry out impedance matching by being placed between an incident field and a body or object to be treated or observed. It is also used to improve a method for contactlessly characterizing a medium to be investigated, via inductive coupling of one or more of the resonators of said array to a probe connected to a reader.

Abstract: Disclosed herein is an antenna device that includes a filter layer, an antenna layer, a divider layer, and ground patterns. The antenna layer has first and second radiation conductors and first and second ground pillars that surround the first and second radiation conductors, respectively. Each of the first and second ground patterns has a first area that overlaps a first space surrounded by the first ground pillars, a second area that overlaps a second space surrounded by the plurality of second ground pillars, and a third area that connects the first and second areas. A width of the third area in a width direction perpendicular to an arrangement direction of the first and second areas is smaller than a width of each of the first and second areas in the width direction.

Abstract: An antenna includes an antenna body and a housing case. The antenna body configured to enter a first mode exhibiting an artificial magnetic conductor character with respect to an electromagnetic wave in a first frequency band and configured to enter in a second mode (TM mode) serving as a resonator for the electromagnetic wave in a second frequency band higher than the first frequency band. The housing case includes a bottom plate on which the antenna body is installed and a side wall provided standing from the bottom plate and spaced with a distance from a periphery of the antenna body. The housing case is a case made of metal including an opening in a face through which the electromagnetic wave enters and exits.
