Engineering the Phase Speed of Surface–plasmon Wave at the Planar Interface of a Metal and a Chiral Sculptured Thin Film

چکیده
The solution of a boundary–value problem formulated for a modified Kretschmann configuration shows that the phase speed of a surface–plasmon wave guided by the planar interface of a sufficiently thin metal film and a chiral sculptured thin film (STF) depends on the vapor incidence angle used while fabricating the chiral STF by physical vapor depoistion. Therefore, it may be possible to engineer the phase speed quite simply by selecting an appropriate value of the vapor deposition angle (in addition to the metal and the evaporant species).

متن کاملDyakonov–Tamm wave at the planar interface of a chiral sculptured thin film and an isotropic dielectric material
Surface waves, named here as Dyakonov–Tamm waves, can exist at the planar interface of an isotropic dielectric material and a chiral sculptured thin film (STF). Due to the periodic nonhomogeneity of a chiral STF, the range of the refractive index of the isotropic material is smaller but the range of the propagation direction in the interface plane is much larger, in comparison to those for the ...
متن کاملMorphological Effects on Surface Plasmon Polaritons at the Planar Interface of a Metal and a Columnar Thin Film
Surface plasmon polaritons (SPPs) at the interface of a columnar thin film (CTF) and metal exist over a range of propagation directions relative to the morphology of the CTF which depends on the tilt of the columns in the CTF. The phase speed of the SPP wave varies mainly as a function of the tilt of the CTF columns. Both the confinement of the SPP wave to the interface and the decay of the SPP...
متن کاملMorphological influence on surface–wave propagation at the planar interface of a metal film and a columnar thin film
The selection of a higher vapor deposition angle when growing a columnar thin film (CTF) leads to surface– wave propagation at a planar metal–CTF interface with phase velocity of lower magnitude and shorter propagation range. Acordingly, a higher angle of plane–wave incidence is required to excite that surface wave in a modified Kretschmann configuration. c © Anita Publications. All rights rese...
متن کاملOptical sensing of analytes in aqueous solutions with a multiple surface-plasmon-polariton-wave platform
The commonly used optical sensor based on surface plasmon-polariton wave phenomenon can sense just one chemical, because only one SPP wave can be guided by the interface of a metal and a dielectric material contained in the sensor. Multiple analytes could be detected and/or the sensing reliability for a single analyte could be enhanced, if multiple SPP-wave modes could be excited on a single me...
