    摘要： Disclosed is an antenna desensitization system and a method for designing an antenna desensitization system. The system and method are operative to provide a configuration and positioning of an antenna desensitizer element, with respect to an antenna, to overcome a frequency detuning experienced during operation of such antenna. The antenna desensitizer element comprises one or a combination of more than one decoupling components selected from the group of a frequency selective surface, an electromagnetic band gap structure, a ferromagnetic material, an anisotropic material, a nanomaterial, a dielectric material, and a conductive material. The system and method are particularly suitable for reducing the antenna frequency detuning effects caused by an external agent, such as a user or operator of a mobile electronics device, during operation of such device.

    摘要： A concealed radar imaging system includes a visible light mirror, a radar device positioned behind the visible light mirror, and a processing circuit coupled to the radar device. The visible light mirror includes a reflective layer configured to reflect visible light, and allow a radar signal to pass therethrough. The radar device is configured to transmit the radar signal, receive a reflection of the radar signal, and generate reflection data based on the reflected radar signal. The processing circuit is configured to control operation of the radar device, receive the reflection data from the radar device, and generate imaging data based on the transmitted radar signal and the reflection data.

    摘要： An artificial medium includes: a dielectric layer having a front surface and a back surface; a plurality of first grid lines respectively formed on the front surface and the back surface and extending in a first direction and a plurality of second grid lines extending in a second direction different from the first direction; and electrically conductive elements respectively formed on the front surface and the back surface of the dielectric layer and located in areas where the first grid lines intersect the second grid lines, wherein when an electromagnetic wave propagated in the direction of the thickness of the dielectric layer is incident, a current excited by the electromagnetic wave is increased in a prescribed operating frequency and a current loop is formed in a plane parallel to the direction of the thickness.

    摘要： Methods and apparatus for a multilayer millimeter-wave window according to various aspects of the present invention operate in conjunction with a multilayer window that is substantially transparent to a passing millimeter-wave. The window may include multiple perforations in a thermally conductive element to be disposed in the path of the passing wave. A dielectric is positioned between each thermally conductive element and acts as a seal between wave source and an ambient environment. The window may also be configured to conform to a contoured surface or structure.

    摘要： A radome uses traditional continuous heating wires mixed with detuned dipoles between heating wires and can be placed at any chosen distance from an array antenna or FSS. The continuous heating wires add a reactive component to the incident field phase, which is effectively cancelled out by the detuned dipoles which provide a capacitive component. The orthogonal components of the incident field are transmitted with very small losses over a wide number of scan angles. These heating and detuned dipoles can be printed on low loss dielectric materials. In addition, the printed elements of this radome can be scaled to operate over a chosen frequency band.
