A comparison of methods for calculating the field from a single dipole source in the proximity of an infinite periodic artificial material (PAM) is given. A direct plane-wave expansion method (PWM) is compared with the ldquoarray scanning methodrdquo (ASM). The ASM is shown to be the most efficient method for sources that are close to the PAM, since it only requires integration in the wavenumber plane over the Brillouin zone rather than over the entire wavenumber plane. It is also shown how the… CONTINUE READING
