Description

XL Scientific submits this proposal to develop a computational electromagnetic (CEM) software simulation toolkit. 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.<br>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.<br>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.
