Claim:
1. An apparatus for manipulating electromagnetic waves of a predetermined wavelength comprising: 1) a first emitting source arranged to produce a single first electromagnetic beam; 2) at least one second emitting source arranged to produce at least one second electromagnetic beam; 3) first phase means for adjusting phase of the at least one second electromagnetic beam; 4) the first emitting source and the at least one second emitting source arranged such that the first beam has beam width smaller than or substantially the same as the wavelength along a predetermined first direction and the first beam and one of the at least one second beam are spaced apart by a distance smaller than or substantially the same as the wavelength along the first direction; 5) the first emitting source and the at least one second emitting source arranged such that power of the first beam is at least twice power of each of the at least one second beam; and 6) the apparatus arranged such that the first beam and the at least one second beam mix with each other to produce a third beam, wherein propagation characteristics of the third beam is influenced by the at least one second beam.
