A display of wavelength elements can be produced from resonant structures
that emit light (and other electromagnetic radiation having a dominant
frequency higher than that of microwave) when exposed to a beam of
charged particles, such as electrons from an electron beam. An exemplary
display with three wavelengths per pixel utilizes three resonant
structures per pixel. The spacings and lengths of the fingers of the
resonant structures control the light emitted from the wavelength
elements. Alternatively, multiple resonant structures per wavelength can
be used as well.
