A model of a large-area planar plasma producer based on surface wave propagation in a plasma-metal structure with a dielectric sheath

Abstract

A theoretical model of a large-area planar plasma producer based on surface wave (SW) propagation in a plasma-metal structure with a dielectric sheath is presented. The SW which produces and sustains the microwave gas discharge in the planar structure propagates along an external magnetic field and possesses an eigenfrequency within the range between electron cyclotron and electron plasma frequencies. The spatial distributions of the produced plasma density, electromagnetic fields, energy flow density, phase velocity and reverse skin depth of the SW are obtained analytically and numerically.

Plasmas meet plasmonics

“…For example, for metallic nanorods, two plasmon modes are present, namely a longitudinal mode (polarisation parallel to the long axis, red shifted) and a transverse mode (polarisation perpendicular to the long axis, blue shifted) [78]. Here we stress that quite similar polarisation effect happen in (gaseous) plasma waveguides which determine their eigenmodes [56].…”

“…As noted in Section 1.2, a surface wave sustained discharge [56,57] is a plasma generated by evanescently decaying EM surface waves propagating along a discharge tube [58,59], an example is shown in Figure 4a. A typical set-up is shown in Figure 4b [45,46].…”

Customizing electron confinement in plasma-assembled Si/AlN nanodots for solar cell applications

“…Size-uniform Si NDs on an AlN buffer layer have been synthesized by means of the low-frequency inductively coupled plasma ͑ICP͒ assisted magnetron sputtering deposition. [17][18][19][20][21] The buffer layer made of the X-V compound AlN has been chosen because of its many merits such as a very high dielectric constant ͑8.5͒, excellent thermal conductivity ͑3.2 W/cm K͒, and high refractive index ͑2.15͒. [22][23][24] In addition, AlN has a hexagonal wurtzite crystal structure and its lattice constants, a and c, are 3.112 and 4.982 Å, respectively.…”

Transmission of electromagnetic waves through a two-layer plasma structure with spatially nonuniform electron density

“…In particular, the electron temperature and collisions effects have been neglected. These effects can influence the transmission of electromagnetic waves through the structure and loss of wave electromagnetic energy, and were studied by previous authors [24,32]. We also limited our study by the case when the local plasma frequencies ω pe (x) in the dense-plasma layer are larger than the wave frequency.…”
