Microstripline Circuits for Microwave Plasma Discharges

IntroductionWidely used in a variety of products and processes, plasmas are generated by applying a voltage between electrodes to facilitate gas ionization. The voltage may be static (DC) or varying at a fixed rate that can be in the RF range (<100 KHz) or as high as tens of MHz in frequency. Typical plasmas have a characteristic physical dimension...

Efficient Selection of Carbon Nanotubes by Desired Properties

IntroductionIn the beginning powder form, carbon nanotubes (CNTs) have a wide range of physical dimensions and electrical properties at the level of individual CNTs. A number of researchers have tried various methods of selecting and manipulating (CNTs) produced in batch quantities. However, these processes do not select CNTs by specific dimensions,...
