Abstract:
1. A method of applying a Faraday cage to a lucent resonator, the resonator having a void containing microwave-excitable material and being adapted for microwave resonance in the resonator and within the Faraday cage for driving a light emitting plasma in the void, the method consisting in the steps of: deposition of a conductive material onto the lucent resonator; applying, patterning and developing a photoresist material over the conductive material to leave the conductive material exposed where it is not required; removing the conductive material where not required and the photoresist material from the required conductive material, leaving a reticular network of conductive material providing a Faraday cage and depositing a layer of protective material over the cage of conductive material wherein a ring of the conductive material, either in continuous form or as part of the reticular network, is left uncovered by the protective material and a fixture ring is soldered or brazed to the exposed conductive material.
