In this e-book the authors current numerous examples of innovations used to beat the Abby diffraction restrict utilizing flat and 3D diffractive optical parts, photonic crystal lenses, photonic jets, and floor plasmon diffractive optics. The constructions mentioned can be utilized within the microwave and THz variety and in addition as scaled versions for optical frequencies. Such nano-optical microlenses will be built-in, for instance, into latest semiconductor heterostructure systems for next-generation optoelectronic applications.
Chapter 1 considers flat diffractive lenses and leading edge 3D radiating buildings together with a conical millimeter-wave Fresnel quarter plate (FZP) lens proposed for subwavelength focusing. In bankruptcy 2 the subwavelength focusing houses of diffractive photonic crystal lenses are thought of and it's proven that not less than 3 kinds of photonic crystal lens are attainable.
With the purpose of accomplishing subwavelength focusing, in bankruptcy three an alternate mechanism to supply photonic jets at Terahertz frequencies (terajets) utilizing 3D dielectric debris of arbitrary dimension (cuboids) is taken into account. A scheme to create a 2nd “teraknife” utilizing dielectric rods is usually mentioned. within the ultimate bankruptcy the profitable model of free-space 3D binary phase-reversal conical FZPs for operation on floor plasmon-polariton (SPP) waves demonstrates that analogues of Fourier diffractive parts will be constructed for in-plane SPP 3D optics.<
ing thought, modelling and test, this ebook could be a invaluable source for college kids and researchers engaged on nanophotonics and sub-wavelength focusing and imaging.

1 Ray-trasing of sphere focusing: RIC = 1,5 (left) and RIC = 3 (right) But the method used in  is invalid for particle with diameter less than 2 wavelengths. Because of the scale of the problem, this focus point does not obey to the geometrical laws for dielectric spherical particles with a diameter size that can be compared with the wavelength. Thus these effects can not be predicted on the basis of geometrical optics or scalar diffraction theory, and it is essential to study the propagation of electromagnetic waves through such elements using the Maxwell equations.
