Efficient Broadband Electrically Small Antenna Arrays

HyPerComp proposes to build on its strengths in developing high order discontinuous Galerkin (DG)-based methods, uncertainty quantification and reduced order-basis methods and investigate some novel ideas for modeling large-scale antenna/structure coupling problems of interest to the Navy. Some of the technologies to be considered are, 1) Physics-based accurate modeling of EM scattering from complex targets, 2) uncertainty estimation based on a chaos polynomial expansion procedure, 3) a reduced order-basis method (RBM) for greatly minimizing the computational burden of generating large data domes, and 4) exploiting the advances in graphic processing unit (GPU) computing for dramatic speedups in computation over conventional central processing unit (CPU) type computing. In the Phase II effort, the end goal is to advance the state of the art in these areas to provide user-friendly, turn key computing platforms for routine computation of physics-based, accurate, full wave solutions for Navy objects of interest at greatly reduced computational run times over current practice.
