1. An apparatus, comprising:

  • a non-conductive substrate; and

    a plurality of cells including conductive members coupled to the non-conductive substrate, wherein the conductive members are arranged to form a first discontinuous mesh, wherein regions between the conductive members of the first discontinuous mesh include a phase change material, wherein the phase change material undergoes a phase transition from substantially non-conductive to substantially conductive, and wherein the first discontinuous mesh permits propagation therethrough of a first electromagnetic waveform having a first wavelength and substantially blocks propagation therethrough of a second electromagnetic waveform having a second wavelength that is different than the first wavelength.
