The computational efficiency of continuous Galerkin, compact discontinuous Galerkin and hybridizable discontinuous Galerkin is compared for 2D scattering problems in unbounded domains. High-order polynomial approximations out-perform low-order approaches for a wide range of wavelengths, requiring less degrees of freedom, and less runtime, for a given accuracy, for both continuous and discontinuous methods. Continuous Galerkin and hybridizable discontinuous Galerkin exhibit comparable efficiency for high-order approximations, providing similar levels of accuracy for the same computational cost and clearly outperforming compact discontinuous Galerkin.
