Abstract: 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.

Abstract: 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.

Abstract: Polarization current antennas include an arc-shaped dielectric radiator, electrodes, and a feed network. The electrodes and feed network are configured to generate an electric field within the dielectric radiator. The electrodes are positioned on the top and bottom of the dielectric radiator and the electromagnetic radiation is emitted through the outer surface thereof. Phase differences between excitation signals supplied to the electrodes may be selected so that a speed of a volume polarization distribution current pattern that is generated in the dielectric radiator will be substantially equal to the speed of light within the dielectric radiator. The antenna emits both conventional spherically decaying electromagnetic radiation and as non-spherically decaying electromagnetic radiation that decays as a function of distance d at a rate that is less than 1/d2. The non-spherically decaying radiation includes a highly focused beam that has an angular beamwidth that narrows as the distance d increases.

The volume polarization current radiator, includes a dielectric solid (such as a dielectric strip), and a plurality of closely-spaced excitation elements (24), each excitation element (24) being configured to induce a volume polarization current distribution in the dielectric solid proximate to the excitation element when a voltage is applied to the excitation element. The feed network is coupled to the volume polarization current radiator.

Abstract: An apparatus and method for a radiation source involving phase fronts emanating from an accelerated, oscillating polarization current whose distribution pattern moves superluminally (that is, faster than light in vacuo). Theoretical predictions and experimental measurements using an existing prototype superluminal source show that the phase fronts from such a source can be made to be very complex. Consequently, it will be very difficult for an aircraft imaged by such a radiation to detect where this radiation has come from. Moreover, the complexity of the phase fronts makes it almost impossible for electronics on an aircraft to synthesize a rogue reflection. A simple directional antenna and timing system should, on the other hand, be sufficient for the radar operators to locate the aircraft, given knowledge of their own source's speed and modulation pattern.

Abstract: The fact that the intensity of the pulse decays more slowly than predicted by the inverse square law is not therefore incompatible with the conservation of energy, for it is not the same wave packet that is observed at different distances from the source: the wave packet in question is constantly dispersed and reconstructed out of other waves. The cusp curve of the envelope of the wavefronts emanating from an infinitely long-lived source is detectable in the radiation zone not because any segment of this curve can be identified with a caustic that has formed at the source and has subsequently travelled as an isolated wavepacket to the radiation zone, but because a certain set of waves superpose coherently only at infinity.
