We are a recently-formed R&D company whose staff have maintained close relationships with the Electrical and Computer Engineering departments at several universities. These connections allow us to remain aware of and to apply the results of recent research in CEM simulation technology and to utilize the expertise resident at these universities. Large and complex antennas are commonly used in airborne platforms to transmit and receive signals. A variety of advanced antennas are installed on high-performance aircraft, providing radar and wireless communications. Conducting full wave performance analysis on the antennas on such a platform is challenging. Numerical techniques face technical difficulties in terms of the computational cost, desired accuracy, modularity, and stability of formulations. XL Scientific proposes a hybrid approach to simulating environment-specific gain patterns for electrically large antenna systems. The approach is based on development of a multi-region multi-method CEM software simulation toolkit that can perform full wave analysis to study the in-situ antenna performance on platforms with realistically complex shapes and materials. Our approach provides considerable cost-savings over measurement-based antenna characterization, as well as time-savings, potentially accelerating the development schedule during the system design phase. Benefits: A completed multi-region multi-method computational electromagnetic (CEM) software simulation toolbox will provide a comprehensive M&S capability for antenna characterization. We will market the commercial tool to both industry companies involved with aircraft or other complex antenna systems and other military branch airborne elements as a way to save time and money in antenna design and characterization, advancing schedules in fielding new systems and shortening the time to respond to capability gaps. We envision a high demand in our tool from industry based on the capability for modeling in-situ performance and co-site interference in large antenna systems - larger systems than can be modeled in other tools, with faster runtimes than are possible from leveraging advanced high performance computing (HPC) architectures alone. We also expect an equally high level of interest from other branches of the military based on the need for virtual prototyping to advance design processes and to identify electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues early in the design phase. We anticipate that our tool will out-perform other commercial antenna analysis software packages in terms of the large problem size that our tool will be able to solve as compared to other commercial tools.
