Focusing light into a small spot is vital in many research and industrial fields. In principle, the diffraction nature of light restricts the achievable size of a focal spot referred to as the diffraction limit. Cylindrical vector beams have a promis

In a severe sea state, nonlinear wave loads can excite resonant responses of floating wind turbines either at high (structural) or low (rigid body motions) natural frequencies. In the present work, a computational fluid dynamics (CFD) model and an en

Summary Holography was originally invented for the purpose of magnifying electron microscopic images without spherical aberration and has been applied to photography for recording and reconstructing three-dimensional objects. Although it has been att

With an increase in the size and shape complexity of optical surfaces, the periodic structure on the optical surface can have significant effects on the beam profile, which propagates in the optical system. This necessitates a quantitative analysis o
We introduce quantum plasmonic sensing—a technology that has recently emerged in the field of nano-optics with a range of practical applications. This new technology has been developed with the aim to exploit both plasmonic and quantum features sim

The experimental and theoretical investigations of attosecond pulses diffraction describe one unexpected parabolic deformation of their intensity profile at few diffraction lengths. This deformation was called by some authors λ3 diffraction. In our

In this chapter I discuss the dependence of image formation on the nature of light itself. Geometrical optics is no longer sufficient to predict the relationship between the object and the image when the object's size approaches the wavelength of lig

[EN] In this work, we report the focusing effect of a 2D sonic crystal cuboid. The proposed sonic composite lens is vertically extended from a 2-D flat Phononic Crystal Structure, but it is found to be able to focus waves in a three-dimensional manne
