Abstract
We computationally investigate the excitation of subradiant modes and Fano resonances of arrays of simple antenna elements with subwavelength dimensions. We show that periodic arrangements of dipoles on a flat surface provide a highly flexible approach for developing a range of metasurfaces with high sensitivity to both the wavelength of the incident radiation and angle of incidence. This provides a platform for the development of a range of metasurfaces with a wavelength-tunable sensitivity to phase gradients in an incident field.
