Abstract:
1. A microcavity plasma lamp, comprising: a first metal and metal oxide layer defining a first array of microcavities and an oxide encapsulated first thin metal electrode; a second metal and metal oxide layer defining a second array of microcavities and an oxide encapsulated second thin metal electrode, said second metal and metal oxide layer being separated from said first metal and metal oxide layer such that there is no direct physical contact between first and second metal and metal oxide layers; a packaging containing said first and second metal and metal oxide layers; and plasma medium contained within said packaging; wherein said first and second metal and metal oxide layers are configured and arranged to create a varying ratio of electric field strength and total gas pressure (E/p) between the first and second metal and metal oxide layers (where E is the electric field strength and p is the total gas pressure).
