A novel all-dielectric metasurface based on reflection cancelling Huygens' source pair is proposed for mm-wave beam-forming applications, and demonstrated using full-wave simulations. The metasurface is realized using an elliptical resonator connected with its neighbor using four dielectric bridges to provide mechanical stability. The quarter-wavelength spaced resonator pair is next used to achieve reflection cancelling, thereby matching the structure over a large bandwidth. By exploiting resonator ellipticities, transmission phase is engineered. Its application in beam-forming is next illustrated by realizing a monopulse pattern as an example.
