We study the properties of surface solitons generated at the edge of a semi-infinite photonic lattice in nonlinear quadratic media, namely two-color surface lattice solitons. We analyze the impact of phase mismatch on the existence and stability of nonlinear surface modes and find novel classes of two-color twisted surface solitons, which are stable in a large domain of their existence.

quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...

I n th i s paper we present a method of indexing color im.ages based o n color surface reflectance classes. Specifically. we analyse the d i s t r ibu t iom f r o m m e m bers of a surface color class in a chrominance-based color space and show tha t they fo rm, collinear clusters under identical i l luminat ion . W e also design a n optima l color space based o n the Fisher d iscr iminant crit...
