TY  - JOUR
AB  - When conductor or semiconductor materials areexposed to microwave radiation in different atmospheres (Ar, He,N2, and O2+N2) intense discharge phenomena are observed. Thedischarge phenomena, generated when strips of the metals Fe, Al,and Zn or particles of the semiconductor SiC are irradiated withmicrowaves, are characterized experimentally using spectrumacquisition and analysis. Filamentary discharge is observed inan Ar atmosphere while spark discharge is observed in He, N2,and O2+N2 atmospheres. The spectral lines of the dischargesare concentrated mainly in the visible region, but there are alsopeaks in the ultraviolet region. The nature of the discharge andthe specific details of the spectra are influenced by: 1) the targetmetal or semiconductor used; 2) the atmosphere; and 3) themicrowave field characteristics. The spectra always consist of twoparts: one corresponding to the target metal or semiconductorirradiated by the microwaves and the other due to the formationof the high-energy excitation states of atoms, molecules, andions induced in the gaseous atmosphere. The microwave-induceddischarge and the corresponding luminous and plasma effectshave potential uses as energy sources in many applicationsincluding chemical or photocatalytic enhancement of reactionsand the destruction of volatile organic compounds for whichpreliminary results are encouraging.
