1. An apparatus comprising:

  • an antenna;

    at least one electrochromic surface disposed proximal to the antenna wherein the at least one electrochromic surface has at least one operational mode comprising energizing the at least one electrochromic surface to cause the at least one electrochromic surface to become reflective to at least some radio frequency energy emissions to thereby cause at least part of the radio frequency emissions from the antenna to be reflected in a direction and thereby contribute to at least one null or peak of a radio frequency beam in a selected direction.
