Abstract
The invention provides a microplasma photonic crystal for reflecting, transmitting and/or storing incident electromagnetic energy includes a periodic array of elongate microtubes confining microplasma therein and having a column-to-column spacing, average electron density and plasma column diameter selected to produce a photonic response to the incident electromagnetic energy entailing the increase or suppression of crystal resonances and/or shifting the frequency of the resonances. The crystal also includes electrodes for stimulating microplasma the elongated microtubes Electromagnetic energy can be interacted with the periodic array of microplasma to reflect, transmit and/or trap the incident electromagnetic energy.
