Effect of Waveguide Boundry Conditions on the Backscatter of Lower Hybrid Waves
نویسندگان
چکیده
The effect of waveguide boundary conditions on the spectrum resulting from the backscatter of lower hybrid waves near a waveguide array is calculated. It is found that the resulting k spectrum is peaked at multiples of 7r/b, where b is the waveguide width. This calculation may partially explain recent lower hybrid heating results on Alcator A.

In this paper, free longitudinal vibration of nanorods is investigated from the wave viewpoint. The Eringen’s nonlocal elasticity theory is used for nanorods modelling. Wave propagation in a medium has a similar formulation as vibrations and thus, it can be used to describe the vibration behavior. Boundaries reflect the propagating waves after incident. Firstly, the governing quation of nanoro...

متن کاملLow loss coupler to interface silicon waveguide and hybrid plasmonic waveguide
A metallic coupler is proposed to interface a silicon on insulator (SOI) waveguide with a narrow hybrid plasmonic waveguide (200× 200 nm). The device operation is investigated and optimized to attain the best tradeoff between the mode confinement and the propagation loss. Calculations reveal that a high confinement and low loss of the energy is achieved from a silicon slab waveguide into the di...
