Latest Patents

One of Bernhardt's latest patents is the "Rocket exhaust driven amplification (REDA) of VLF waves in space." This invention describes a method and apparatus that utilizes a VLF transmitter, a VLF receiver, and/or a low earth orbit satellite equipped with a rocket engine. The technology converts a VLF wave transmitted into space into an ambient wave, which serves as a signal wave for a whistler traveling wave parametric amplifier. The rocket exhaust generated in atmospheric plasma provides kinetic energy that acts as a Lower Hybrid wave source. This source produces a Lower Hybrid wave, which functions as a pump wave for the parametric amplifier. The nonlinear mixing of the signal wave and the pump wave in the atmospheric plasma amplifies the ambient wave while generating an idler wave and a parametrically amplified wave. This amplified wave has the potential to reduce the density of energetic protons or killer electrons in the Van Allen radiation belt and enhance communications between the VLF transmitter and receiver.

Another significant patent is the "Apparatus for radar target cloaking using polyhedral conducting mesh." This invention involves an apparatus designed to interfere with and cancel electromagnetic reflections from conducting objects, such as solid or hollow conducting spheres. By placing a polyhedral conducting mesh around the conducting sphere, the reflection of an incident electromagnetic wave can be reduced or canceled. The induced electric fields between the conducting mesh and the internal conducting sphere may interfere with and potentially cancel the incident electromagnetic wave, thereby minimizing reflection. The polyhedral conducting mesh can be tuned to target specific frequencies for optimal performance.
