Beschreibung
Zusammenfassung:A material is provided for switching dielectric constant between distinct first and second values responsive to electromagnetic radiation having a specified energy. The material includes a medium transparent to the radiation and a plurality of particulates. Each particulate has a dipole that assumes one of distinct first and second parameters that correspond to the first and second values. The particulates are suspended within the medium. The parameters are either dipole span or charge strength. The dipole of each particulate sets to the first parameter by default and sets to the second parameter in response to the radiation. The particulates can be composed from undoped semi-insulating gallium arsenide. The medium can be polymethylmethacrylate, for example.
