摘要: Various aspects directed towards an integrated transverse electromagnetic (TEM) transmission line structure for probe calibration are disclosed. In one example, the integrated TEM transmission line structure includes a printed circuit board (PCB) and an air-dielectric coplanar waveguide (CPW). For this example, the air-dielectric CPW includes an air trace in a cutout slot of the PCB. In another example, a method is disclosed, which includes forming an air-dielectric CPW on a PCB in which the air-dielectric CPW includes an air trace in a cutout slot of the PCB. In a further example, an integrated TEM transmission line structure includes an air-dielectric CPW with an air trace. For this example, a first connector is electrically coupled to a first end of the air-dielectric CPW, and a second connector is electrically coupled to a second end of the air-dielectric CPW.

摘要: Embodiments described herein relate to apparatus for measuring and characterizing performance of augmented and virtual reality waveguide structures utilizing glass substrates. The waveguide performance measuring systems generally include a light source configured to direct light towards an incoupling grating area on waveguide and one or more light detectors configured to collect light from an outcoupling grating area on a second side of the waveguide. The light source and one or more light detectors are disposed on one or more adjustable stages positioned about the waveguide. In certain embodiments, the one or more adjustable stages are configured to move in a linear fashion or revolve and/or rotate around the waveguide in an orbital motion.

摘要: Aspects of the subject disclosure may include, for example, an antenna system that includes a selector and a dielectric antenna array. The selector is coupled to a number of dielectric cores and selectively launches electromagnetic waves on a selected dielectric core of the dielectric cores. The selected dielectric core corresponds to one of the dielectric cores, and the electromagnetic waves propagate along the selected dielectric core without requiring an electrical return path. The dielectric antenna array is coupled to the dielectric cores and includes a number of dielectric antennas, wherein a dielectric antenna of the dielectric antennas transmits, in response to the electromagnetic waves received from the selected dielectric core, a controllable beam. Other embodiments are disclosed.

摘要: The present disclosure provides systems and methods associated with mode conversion for electromagnetic field modification. A mode converting structure (holographic metamaterial) is formed with a distribution of dielectric constants chosen to convert an electromagnetic radiation pattern from a first mode to a second mode to attain a target electromagnetic radiation pattern that is different from the input electromagnetic radiation pattern. A solution to a holographic equation provides a sufficiently accurate approximation of a distribution of dielectric constants that can be used to form a mode converting device for use with one or more transmission lines, such as waveguides. One or more optimization algorithms can be used to improve the efficiency of the mode conversion.

摘要: Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.
