Abstract: A reflectarray is designed for polarizationdependent beam deflection at 1 THz. Each unit cell is composed of two sets of dipole resonators, corresponding to orthogonal polarizations. The orthogonal dipoles are arranged in two interlaced triangular-lattice arrays. One subarray containing multiple unit cells provides a gradient phase response to complete a 2π phase cycle over its length. This design demonstrates that it is possible to separate the polarization components of an incident beam by deflecting them into two different directions in a given plane. Numerical results predict successful implementation of the principle with available materials and within realistic manufacturing tolerances for operation at a frequency of 1 THz.
