Radiation of surface polaritons by an annular beam coaxially enclosing a cylindrical waveguide
A. A. Saharian, G. V. Chalyan, L. Sh. Grigoryan +2
We investigate the radiation of surface polaritons by an annular beam that coaxially encloses a cylindrical waveguide surrounded by a homogeneous medium. By using the Green dyadic,…
