摘要： Polarization current antennas comprise a dielectric radiator that extends along a z-axis, polarization devices that are positioned adjacent the dielectric radiator along the z-axis that are configured to polarize respective portions of the dielectric radiator and a feed network that is configured to excite the polarization devices with an RF signal to generate a polarization current wave that propagates in the z-axis direction through the dielectric radiator, with acceleration, at (1) a first variable speed that does not decrease as the wave moves along a first portion of the dielectric radiator and that does not increase as the wave moves along the remainder of the dielectric radiator, (2) a second variable speed that does not decrease as the wave moves along the entirety of the dielectric radiator or (3) a third variable speed that does not increase as the wave moves along the entirety of the dielectric radiator.

摘要： An printed circuit board (PCB) assembly and method of assembling the same for a high-speed, short-reach communication link are described that provide a mechanism for transmitting radio frequency (RF) waves from one digital electronic component of the PCB assembly to another, where the second digital electronic component is located either on the same PCB assembly or on a second PCB assembly. The assembly includes a PCB having multiple layers and a digital electronic component supported by the PCB. At least one of the layers defines a channel that confines RF waves therein. An RF antenna in communication with the digital electronic component extends into the channel, and the RF antenna transmits RF signals generated by the digital electronic component into the channel as RF waves or receives RF waves via the channel and conveys corresponding RF signals to the digital electronic component.

摘要： A multiple-feed antenna system includes a primary reflector that directs signals along a primary RF signal path and a subreflector assembly movable between a first position and a second position. When the subreflector assembly is in the first position, the subreflector assembly redirects signals traveling along the primary RF signal path to a first RF signal path. When the subreflector assembly is in the second position, the subreflector assembly redirects signals traveling along the primary RF signal path to a second RF signal path. The multiple-feed antenna system further includes: a first feed that intersects the first RF signal path and that communicates signals within a first frequency range; a second feed that intersects the second RF signal path and that communicates signals within a second frequency range; and an actuator that moves the subreflector assembly to the first position and to the second position.

摘要： An apparatus for generating electromagnetic radiation comprises a polarizable or magnetizable medium. A polarization or magnetisation current can be generated, in a controlled manner, whose distribution pattern has an accelerated motion, so that non-spherically decaying and intense spherically decaying components of electromagnetic radiation can be generated. The coordinated motion of aggregates of charged particles can give rise to extended electric charges and currents. The charged distribution patterns can propagate with a phase speed exceeding the speed of light in vacuo and that, once created, such propagating charged patterns act as sources of electromagnetic fields in precisely the same way as any other moving sources of these fields. That the distribution patterns of these sources travel faster than light is not, of course, in any way incompatible with the requirements of special relativity. The superluminally moving charged pattern is created by the coordinated motion of aggregates of subluminally moving particles.
