1. A non-skid, radar absorbing system disposed adjacent a substrate, the system comprising:

  • an absorbing layer having a thickness t1, a selected magnetic permeability μ

    1 and permittivity ε

    1 juxtaposed with the substrate; and

    a non-skid matrix layer having a thickness t2, a selected magnetic permeability μ

    2 and permittivity ε

    2 disposed adjacent the absorbing layer, the system having electrical and magnetic characteristics μ

    , ε

    that are tuned, and the thicknesses t1, and t2 are selected such that incident wavelength energy at discrete or broadband frequencies is at least partially absorbed.
