摘要： A reactive circuit is disclosed as part of a method and system for generating high-density plasma that does not require the use of a dynamic matching network for directly driving a plasma exhibiting a dynamic impedance. The reactive network is designed to provide a small total reactance when the plasma reactance is at a first plasma reactance and presents a reactance that does not exceed a specified limit at a second plasma reactance. The first and second plasma reactance span a substantially fraction of an expected dynamic plasma reactance range. The first and second plasma reactance values may, for example, correspond to a high-expected plasma reactance limit and a low expected plasma reactance limit respectively or the first plasma reactance may correspond to an average expected plasma reactance.

摘要： A system (10) for information transmission having a plasma antenna (5), including an electrodeless plasma tube (2), and a power source effective to generate an electromagnetic field to cause ionisation of material within the tube so as to form the antenna for one or both of either sending or receiving signals, wherein the electromagnetic field is applied to a portion only of the tube. The system preferably includes a terminal (1) arranged about a base of the tube for establishing the electromagnetic field upon application of power from the power source, to induce surface wave ionisation within the tube.

摘要： A rugged telephone antenna device (70) for transmitting a short pulse duration signal of predetermined radio frequency that eliminates a trailing antenna resonance signal. The device includes a flexible or protected gas filled tube (74); a voltage source for developing an electrically conductive path along a length of the tube corresponding to a resonant wavelength multiple of the predetermined radio frequency; and a signal transmission source coupled to the tube for supplying a radio frequency signal to the conductive path for antenna transmission. A method for transmitting a short pulse signal without a trailing residual signal is also provided.

摘要： A plasma generating apparatus is provided with an impedance matching member, which is connected to a feeding line that supplies an antenna element with a high frequency signal, and has variable characteristic parameters for impedance matching; a distribution wire, which is arranged corresponding to the impedance matching member and connects the impedance matching member with at least two antenna elements; and a control section which changes at the same time impedance matching statuses of at least the two antenna elements connected to the impedance matching member through the distribution wire by changing the characteristic parameters of the impedance member. Thus, the number of impedance matching devices is smaller than that of the antenna elements, and a mechanism relating to impedance matching is made relatively small.
