The project objectives are to (a) develop the simulation capability for modeling superconducting quantum interference filter devices and the related B field antennas, (b) make appropriate designs of co-mingled E and B antennas, and (c) experimentally verify and improve these designs. The numerical simulation will also include the superconducting and quantum mechanic effects in the B field antennas; thus, this project will provide a new tool to determine the optimal configurations of individual E and B field antennas and the arrays formed by such antennas. In Phase 1, we will develop an initial simulation capability for both electric and magnetic field antennas in the near field based on our enhanced new commercial electromagnetic field software package Wavenology EM. With this tool we will determine the mutual coupling and isolation levels from a variety of combinations of E field and B field transmitters/receivers, and the dependence on scanning parameters such as the scan angle. By the end of Phase 1, we will have several candidates for the co-mingled E and B field antennas. Benefits: The anticipated benefit is the development of minimally coupled E and B field antennas for low-frequency communications, and the new modeling capability. This will facilitate a wide variety of DoD applications where low-frequency communications must be provided in a limited space. Civilian applications include mobile communications and geophysical localization. Return
