Near-Field Optical Microscopy of Surface Plasmon Polaritons Nano-Optics
Near field optical microscopy techniques can be employed to characterize surface plasmon polaritons phenomena. These studies have set the stage for the current surge in the nano-optics field. In this chapter experiments and numerical developments conducted to the understanding of this area are outlined. Furthemore a scanning near-field microwave microscope is presented as an alternative techniq...
متن کاملNear - field optical measurement of the surface plasn
The inlensity of the evanescent elmromagnetic wave of optically C ~ E ~ K U surface plasmons was measured directly using a scanning tunneling optical rnlcrmcope (STOM) setup. When resonan1 coupling of the driving field to the surface plasrnons was achteved, the measured tntensrty was increased by a factor of 30 larger than the corresponding evanescent wave intensity on a bare glass surface, in ...
متن کاملNear-field surface plasmon field enhancement induced by rippled surfaces
The occurrence of plasmon resonances on metallic nanometer-scale structures is an intrinsically nanoscale phenomenon, given that the two resonance conditions (i.e., negative dielectric permittivity and large free-space wavelength in comparison with system dimensions) are realized at the same time on the nanoscale. Resonances on surface metallic nanostructures are often experimentally found by p...
متن کاملThe origin of interferometric effect involving surface plasmon polariton in scattering near-field scanning optical microscopy.
Scattering near-field scanning optical microscopy (s-NSOM) has been developed to characterize optical near field with spatial resolution on the order of 10 nm. In this work we report investigation of the interferometric patterns commonly occurred in s-NSOM measurements. To reveal the origin of such interference patterns, a simple nanoslit is used. Comparing the measured result with a simplified...
متن کاملNear-field and far-field scattering of surface plasmon polaritons by one-dimensional surface defects
A rigorous formulation for the scattering of surface plasmon polaritons ~SPP’s! from a one-dimensional surface defect of any shape that yields the electromagnetic field in the vacuum half-space above the vacuummetal interface is developed by the use of an impedance boundary condition. The electric and magnetic near fields, the angular distribution of the far-field radiation into vacuum due to S...
