The authors studied the influence of a small resonant surface on the radiation pattern of a monopole wire antenna when the resonant surface was placed in proximity. By discussing both experiment and simulation results, the authors found that the small resonant surface can effectively block the electromagnetic wave with wavelength which is greater than its dimension. The underlying principle is attributed to the nature of resonance. Therefore, a small resonant surface may function as a subwavelength reflector and protect, to some degree, humans from exposure to electromagnetic radiation.
