Superiority of half - wavelength helicon antennae
نویسنده
چکیده
Plasma densities produced by halfand full-wavelength (HW and FW) helical antennae in helicon discharges are compared. It is found that HW antennae are more efficient than FW ones in producing plasma downstream from the antenna. The measured wave amplitudes and the apparent importance of downstream ionization do not agree with computations.

Superiority of half - wavelength helicon antennas
Plasma densities produced by half-and full-wavelength helical antennas in helicon discharges are compared. Contrary to theoretical expectations, half-wavelength antennas are more efficient than full-wavelength ones in producing plasma downstream. This effect is probably caused by capacitive coupling , which interferes with inductive coupling and is not included in the computations.
متن کاملCoupling terahertz radiation between sub-wavelength metal-metal waveguides and free space using monolithically integrated horn antennae.
Broadband horn antennae are presented that efficiently couple terahertz radiation between sub-wavelength metal-metal waveguides and free space. Sub-picosecond terahertz pulses were coupled into and out from sub-wavelength parallel-plate waveguides by using the horn antennae in a terahertz time-domain spectrometer. Monolithic antennae were fabricated at the facets of metal-metal terahertz quantu...
متن کاملThe “ optical lever ” intracavity readout scheme for gravitational - wave antennae
An improved version of the " optical bar " intracavity readout scheme for gravitational-wave antennae is considered. We propose to call this scheme " optical lever " because it can provide significant gain in the signal displacement of the local mirror similar to the gain which can be obtained using ordinary mechanical lever with unequal arms. In this scheme displacement of the local mirror can...
متن کاملGeneralized theory of helicon waves. I. Normal modes
The theory of helicon waves is extended to include finite electron mass. This introduces an additional branch to the dispersion relation that is essentially an electron cyclotron or Trivelpiece– Gould ~TG! wave with a short radial wavelength. The effect of the TG wave is expected to be important only for low dc magnetic fields and long parallel wavelengths. The normal modes at low fields are mi...
متن کاملA developmental study of photosystem I peripheral chlorophyll proteins.
An isolated "native" photosystem I (PSI complex) contains three spectral populations of chlorophyll a antennae (Mullet, Burke, Arntzen 1980 Plant Physiol 65: 814-822). It was hypothesized that nearly one-half of these antennae ( approximately 45 Chl/P(700)) are associated with polypeptides of 21,500 to 24,500 daltons. The present study utilizes two developmental systems to verify this associati...
