Helicon plasma with additional immersed antenna
A ‘primary’ RF power (H-power) at 13.56 MHz is coupled to a plasma source excited by an external double saddle field Helicon antenna. A ‘secondary’ RF power (S-power), also at 13.56 MHz but with variable phase, is additionally coupled by inserting a second antenna in contact with the plasma through one end of the source. The immersed antenna can be grounded or floating, allowing a self-bias to ...
متن کاملInsulated conducting polymers: manipulating charge transport using supramolecular complexes.
Rotaxane structures which provide functional insulation to conducting polymers can provide over a 4000-fold reduction in conductivity over non-rotaxane structures and with electronically active copper ions in the rotaxane units the conductivity increases by more than 80 times relative to the metal-free analog.
متن کاملScattering from Objects Immersed in a Diffusive Medium
The disturbance of the transmission of light through a diffusive medium due to an object hidden in it can be expressed in terms of an effective charge and dipole moment. In the mesoscopic regime, beyond the diffusion approximation, we calculate this effective charge and dipole moment. Various objects are considered: a single point scatterer, a localised density of such scatterers and a small sp...
متن کاملOn Scattering in a Piezoelectric Medium by a Conducting Crack
The work is concerned with the characterization of a Kirchhoff diffraction field in a piezoelectric material. An exact solution is obtained for the full scattering fields around the tip of a semi-infinite crack, which is electrically conducting and is loaded with both SH acoustic incident waves and in-plane electrical incident waves. First, it is found that a conducting crack in a piezoelectric...
متن کاملA Wideband Compact Planar Conical Loop Antenna
This paper reports the design of a wide band planar fed, planar conical loop Antenna. Parametric studies have been carried out to arrive at the optimum antenna dimensions to have a wide impedance bandwidth (VSWR<2). Experimental results confirmed the wide impedance bandwidth.
