Broadband artificial dielectric with dynamically optical control

A device for switching dielectric constant between distinct first and second values responsive to electromagnetic (EM) radiation having a specified energy, said device comprising:

• an electric field source;
• a medium transparent to the EM radiation within said source;
• and
• a plurality of particulates, each particulate having a dipole that assumes one of distinct first and second parameters that correspond to the first and second values, said plurality being suspended within said medium, wherein
• said dipole of said plurality of particulates sets to said first parameter by default and sets to said second parameter in response to the EM radiation, and
• said particulates are composed from at least one of gallium arsenide, gallium phosphide, gallium nitride and silicon carbide.

A method for varying dielectric constant between distinct first and second values responsive to electromagnetic (EM) radiation having a specified energy, said method comprising:

• providing a medium transparent to the EM radiation;
• suspending a plurality of particulates within said medium, each particulate having a dipole that assumes one of distinct first and second parameter that correspond to the first and second values, wherein said dipole of said plurality of particulates sets to said first parameter by default and sets to said second parameterin response to the EM radiation and said particulates are composed from at least one of gallium arsenide, gallium phosphide, gallium nitride and silicon carbide;
• and
• inducing an electric field source proximate to said medium for aligning said dipole of said each particulate.
