Abstract
The Brewster effect plays a significant role in the transmission of electromagnetic waves with a transverse magnetic mode or p-polarization at a specific angle. Here, a transverse electric mode ultrawide-angle ultralow-reflection phenomenon is proposed to realize perfect transparency at ultrawide incidence angles. Theoretical formulae are derived to provide the basis for the ultrawide-angle ultralow-reflection phenomenon and to explain the significant characteristics of achieving an ultrawide-angle transmission response. As a proof of concept, a metasurface with an ultrawide-angle ultralow-reflection response is designed and measured, whose relative permittivity and permeability tensors are tuned by engineering an electric resonator and a magnetic resonator, respectively. This study unveils a new path for the design of ultrawide-angle transparent surfaces.
