Reduction of Mutual Coupling between E and B Field Antennas in SQIF Arrays

Physical Sciences Inc. (PSI), in partnership with the Electrical Engineering Department of the Worcester Polytechnic Institute (WPI), proposes to compute and reduce mutual coupling between E-field antennas (in Transmit mode) and SQUIDs magnetic loops (in Receive mode) for improved signal reception in SQIF arrays. For the computation of the mutual coupling in the near field PSI and WPI will use an exact quasi-analytical model based on Pocklington integral equation (Method of Moments - MoM). The selected electric antenna design will include a PSI patent pending antenna technology that has recently demonstrated excellent performance in antenna arrays for directed energy applications. The proposed research has direct applications to novel antenna technologies for Electronic Warfare (EW, SEWIP), Military Satellite Communications (MILSATCOM), and Signal Intelligence (SIGINT).
