Wave-vector space picture for radiationless focusing and beaming.
Radiationless interference of an electromagnetic wave occurs in the near field when the feature sizes of the waves are at the deep subwavelength scale. We present the propagation in such a regime using a wave-vector space picture. Using this picture, we reproduce the condition to achieve near-field focusing. We also design the initial field distribution needed for near-field beaming, where an i...
متن کاملNull-field radiationless sources: comment.
We elaborate on a recent paper by Hurwitz and Gbur [Opt. Lett.39, 6529 (2014)], dealing with null-field sources. After commenting on their theory in Minkowski space, we show how the theory can be conveniently generalized to the case of curvilinear space.
متن کاملOn Perfect Lenses and Nihility
The canonical problem of a perfect lens with linear bianisotropic materials is formulated. Its solution is shown to be directly connected with the concept of nihility, the electromagnetic nilpotent. Perfect lenses as well as nihility remain unrealizable.
متن کاملPerfect cylindrical lenses.
A slab of negatively refracting material is known to focus light and if 1 n = the focussing will be perfect, producing an image which is an exact replica of the object. Magnifying the image requires a new design concept in which the surface of the negatively refracting lens is curved. Here we show how a hollow cylinder of material can be designed to magnify an image but otherwise with the same ...
متن کاملOpaque perfect lenses
The response of the “perfect lens”, consisting of a slab of lossless material of thickness d with εs = μs = −1 at one frequency ω0 is investigated. It is shown that as time progresses the lens becomes increasingly opaque to any physical TM line dipole source located a distance d0 < d/2 from the lens and which has been turned on at time t = 0. Here a physical source is defined as one which suppl...
