Abstract
A method for dynamically modifying electrical characteristics of a radome (110). The method can interpose a radome (110) in the path of a radio frequency signal (140). At least one electrical characteristic of the radome (110) can be selectively varied by applying an energetic stimulus to dynamically modify a performance characteristic of the radome (110). Electrical characteristic can include a permittivity, a permeability, a loss tangent, and/or a reflectivity. The energetic stimulus can include an electric stimulus, a photonic stimulus, a magnetic stimulus, and/or a thermal stimulus.
