The geometry under consideration consists of a parallel-plate waveguide with an array of subwavelength, complementary metamaterial elements patterned into one of the conducting surfaces. To determine the radiated field, we model each radiating element as a polarizable dipole, and account for mutual interactions among elements via guided and radiated fields by applying a coupled dipole framework.
