Abstract

Study of energy losses during propagation of surface plasmons (SPs) plays an important role for many applications. We measured the attenuation of terahertz (λ=130μm) SPs generated by the Novosibirsk free-electron laser along plane and convex gold surfaces coated with submicron dielectric (ZnS) layers. The optimal dielectric thicknesses d corresponding to the minimum energy losses of SPs, were found. A ZnS coating with d1≈0.025 μm on a plane gold surface reduced the SP attenuation coefficient by 20 % as compared with bare gold; coating with d2≈1 μm on a convex surface lowered the coefficient three-fold.
