Performing accurate simulations of large- and multi-scale electromagnetics problems has far-reaching implications in a variety of engineering and scientific disciplines. The same physics governs a diversity of applications including problems of importance for NAVAIR such as complex radome-antenna and antenna-platform interactions.  Antenna performance characterization is an increasingly important task for NAVAIR as the number and complexity of antenna systems grows.  Simulations are currently suboptimal in the sense that they either lack the required fidelity or simply cannot be executed within the computational and financial resource constraints.  Such simulation problems involve complex materials, multiple feeds and loads, multiscale meshing challenges, and geometries that may exceed 1000 wavelengths in one or more dimensions. IERUS Technologies proposes a radical departure from the standard workflow that has bogged down high accuracy CEM analysis since its inception: eliminate meshing altogether as it is currently known.  To achieve this, in partnership with BYU, the team will implement both surface and volume representation technologies into our V-Lox software.  BYU has developed this technology to make direct use of the underlying CAD.  This means that CAD is perfectly represented and the spline forms making up the CAD are suitable for use in numerical simulation.  Further, BYU has developed a new method for non-conforming volume solutions, thereby greatly simplifying volume-based workflows.  IERUS will transition this technology to our commercial solver V-Lox to obtain geometry-perfect, high-order accurate solutions for large-scale CEM problems.
