Abstract:We report on the concept, generation and first observations of focused surface plasmons on shaped gratings. The gratings patterns are engineered to perform functions such as focusing or directing through noncolinear grating-assisted phasematching. We present local probing of the plasmon propagation by phase sensitive PSTM of the field distribution on engineered gratings showing the focusing of plasmons.
