Verification of goal-oriented HP-adaptivity

The paper presents calculations for the radiation of a loop antenna wrapped around a metallic cylinder into a conductive medium. The problem has been solved analytically by using Fourier transform and Bessel functions. The analytical solution has been used to verify a goal-oriented hp adaptive strategy based on a simultaneous solution of a dual problem, and an hp strategy based on minimizing the projection-based interpolation error of a reference solution.
