    Description

    The Department of Defense (DOD) is seeking proposals for the topic "Numerical Simulation of VLF Antennas in Space Plasma" as part of their SBIR 24.1 BAA. The objective of this research is to develop a multi-scale 3D numerical Electro-Magnetic (EM) plasma simulation capable of resolving a real electric dipole antenna or magnetic loop antenna as well as the electromagnetic radiation produced by the antenna with kilometer-scale wavelengths. The technology is aimed at addressing the threat of energetic electrons to satellites in low Earth orbit and removing them using electromagnetic Whistler waves. The proposed numerical model should be capable of representing antenna concepts in realistic detail while modeling both the local plasma response and the distant radiation, including the wave mode. Antenna concepts include the electric dipole, magnetic loop antenna, magnetic rod antenna, and engineered plasma modification. The end product will be a computer plasma model capable of aiding the design of a space-based antenna immersed in the low or near Earth plasma. The project will be conducted in two phases, with Phase I focusing on identifying and demonstrating the numerical methods to be used, and Phase II delivering a fully functional design tool for modeling antenna concepts. In Phase III, the design tool will be used to design candidate systems for the radiation of radio waves at Very Low Frequency. The project duration and funding specifics are not provided in the document. For more information and to submit proposals, interested parties can visit the DOD SBIR 24.1 BAA topic link on the SBIR website.

    Department of Defense
    The Department of Defense (DOD) is seeking proposals for the topic of "Quantum Enhanced RF Components" in their SBIR 24.4 Annual solicitation. The objective of this research is to utilize quantum phenomenology to create sensitive Radio Frequency (RF) components that can enhance the performance of current communication systems. By lowering the noise levels of these components, weaker signals can be detected, potentially enabling the radar detection of previously unseen targets. The research will focus on developing quantum-based RF components such as amplifiers, mixers, and oscillators that can be integrated with existing systems. The project will be conducted in two phases. Phase I will involve delivering a series of reports outlining the feasibility of the RF component using mathematical models for quantum phenomena. Phase II will require the delivery of a working prototype and a report documenting the prototype's capabilities and any necessary control software. The potential applications of this technology include enhancing the efficacy of security systems that rely on RF detection, minimizing disruptions in police and first responder communications systems caused by RF interference, and improving communication between maritime and aviation vehicles.
