    • A low-temperature, atmospheric-pressure microplasma generator comprises at least one strip of metal on a dielectric substrate. A first end of the strip is connected to a ground plane and the second end of the strip is adjacent to a grounded electrode, with a gap being defined between the second end of the strip and the grounded electrode. High frequency power is supplied to the strip. The frequency is selected so that the length of the strip is an odd integer multiple of ¼ of the wavelength traveling on the strip. A microplasma forms in the gap between the second end of the strip and the grounded electrode due to electric fields in that region. A microplasma generator array comprises a plurality of strongly-coupled resonant strips in close proximity to one another. At least one of the strips has an input for high-frequency electrical power. The remaining strips resonate due to coupling from the at least one powered strip. The array can provide a continuous line or ring of plasma. The microplasma generator can be used to alter the surface of a substrate, such as by adding material (deposition), removal of material (etching), or modifying surface chemistry.
    • 低温大气压微量发生器在电介质基底上包括至少一条金属条。 带的第一端连接到接地平面,并且带的第二端与接地电极相邻,在带的第二端和接地电极之间限定间隙。 高频电源被提供给带。 选择频率使得条的长度是在带上行进的波长的1/4的奇整数倍。 由于该区域中的电场,在条带的第二端和接地电极之间的间隙中形成微米。 微量发生器阵列包括彼此靠近的多个强耦合谐振条。 至少一个条具有用于高频电力的输入。 剩余的条由于至少一个动力带的联接而共振。 阵列可以提供连续的等离子体线或环。 微量发生器可以用于改变基底的表面,例如通过添加材料(沉积),去除材料(蚀刻)或改变表面化学。
