    摘要： A reconfigurable polar molecule includes a symmetric nonpolar molecule portion having an elongated shape defined by a longitudinal axis and lateral axis, the longitudinal axis being longer than the lateral axis; a positive ionically charged group at a first end and a negative ionically charged group at a second end of the longitudinal axis, the positive and negative ionically charged groups forming a permanent dipole; a first bridging group and a second bridging group on opposing ends of the lateral axis, the first and second bridging groups being linear nonpolar groups; and a first support portion bonded to the first bridging group, and a second support portion bonded to the second bridging group, the first bridging group and the second bridging group being nonpolar and having structures that enable free rotation of the symmetric nonpolar molecule portion through the first bridging group and the second bridging group.

    摘要： The present disclosure is directed to a seeker system having an infrared (IR) sensor pedestal, an IR sensor disposed on the IR pedestal and a plurality of radio frequency (RF) antenna elements symmetrically disposed in a circumferential direction around the IR sensor pedestal. The seeker system further includes a plurality of RF waveguiding structures. In an embodiment, each of the RF waveguiding structures have first and second ends and are symmetrically disposed in a circumferential direction around the IR sensor pedestal such that in response to an RF signal incident on a first end of the waveguiding structure, the RF signal is provided to one of the plurality of RF antenna elements such that in response to an RF signal incident on the seeker system from any direction, each of the plurality of RF antenna elements receive the RF signal with a desired phase characteristic.
