Estimation of HIRF transfer functions by a leap-frog discontinuous Galerkin method

In this work, we show some characteristics than enable the efficient and accurate estimation of High-Intensity Radiated Fields transfer functions in complex environments by a leap-frog discontinuous Galerkin method. The conformal truncation of the computational domain, and the selection of different order of the basis functions combined with a local time-stepping technique, permits the computation of challenging test cases. The results have been validated with measurements and to other numerical methods, demonstrating the accuracy, efficiency, and scalability of the approach.
