Radio frequency power distribution

In order to examine the elfect of flow pattern in a reactor, which is a crucially important design factor of an LCVD reactor, it is necessary to examine the profile of deposition in a simple reactor first. A tubular reactor with an external radio frequency power coupling is ideally suited to the study of the distribution of polymer deposition. In such a reactor, 100% of the monomer passes through the luminous gas phase in the reactor, and the situation is very close to the case in which no bypass of monomer occurs. The experimental setup used for...

Spinal cord stimulation (SCS) is a form of therapy used to treat certain types of chronic pain. An array of stimulating metal contacts is positioned in the dorsal epidural space. An electrical field is generated through connection of the contacts with an electrical generator. The leads can be implanted by laminectomy or percutaneously, and the source of power is supplied by an implanted battery or by an external radio-frequency transmitter. The resulting field presumably stimulates DRG axons and dorsal column fibers [41,42]. The goal is to create a field of (tolerable) paresthesias that overlap and cover the anatomic distribution of pain reported by the patient. A temporary trial of stimulation, most commonly performed with percutaneous lead placement, is required to identify patients who might benefit.
