State the relation between object distance, image distance and focal length of a spherical mirror (concave mirror or convex mirror). Calculate the image distance for an object of height 12 mm at a d...
Some of them consider optical fields containing the lattice of vortices generated, for example, by three or more plane or spherical waves interference [6,7,8,9]; or so called composed vortices, i.e., vortices which are generated by two or more overlapping beams [10,11,12,13,14,15,16]...
It does not matter which component is eliminated in the Cartesian rectilinear coordinates because vector differential operations are symmetrical with respect to all spatial variables. However, it is not the case in curvilinear coordinates, in particular, in cylindrical or spherical coordinates. In any ...
