A standard Gaussian beam carrying high speed signals shines on the phase-only SLM to generate the multiple OAM states of Bessel beams in one branch. The European Conference on Optical
Design of Shaped Beam Planar Arrays of Waveguide The Elliotts procedure for the design of a pencil beam waveguide longitudinal slot array has been generalized to encompass the design of shaped beam planar slot arrays. An extended set of design equations, taking into account in an operative way the feeding part of the array, has been devised. From this set of equations, a general and effective design procedure has been set up, shedding

Generation and characterization of focused helical x-ray beamsFor patterning, a 30-keV Ga + focused ion beam (Nova NanoLab 600, FEI) was chosen with a current of 300 pA that results in a nominal beam size of 31 nm. The ZP pattern was written in a single cycle with 30-nm step size and 0.4-ms dwell time, which corresponds to 3.2% overlap and an ion dose of
Jindal Steel and Power - Envisioning successJindal Power Limited is a fully integrated power business that generates economical and efficient electricity through captive and independent production facilities with a
The focused ion beam (FIB) is a powerful piece of technology which has enabled scientific and technological advances in the realization and study of micro- and nano-systems in many research areas, such as nanotechnology, material science, and the microelectronic industry. Recently, its applications have been extended to the photonics field, owing to the possibility of developing systems with
Minerals Free Full-Text Grain Size Distribution and Although clay mineral content in ion-absorbed rare earth ores is crucial for migrating and releasing rare earth elements, the formation, distribution, and migration of clay minerals in supergene rare earth ores have not been fully understood. Therefore, this study analyzes the characteristics of clay mineral type and content, soil particle size, pH value, leaching solution concentration, and
OSA Coherent beam combining with micro-lens arraysA novel, to the best of our knowledge, concept for coherent beam combining is presented based on a simple setup with micro-lens arrays. These standard components are used in a proof-of-principle experiment for both coherent beam splitting and a combination of 5×5 beams. Here a combination efficiency above 90% is achieved. We call this novel concept mixed aperture.
Considering a cluster of GBs that transmit from point along the direction of arrow, the electric field at original location (point ) can be described  where is beam waist radius; and are horizontal size and vertical size in the initial location. The normalized beam intensity distribution in any paraxial intersecting surface of the slab system can be described by the generalized Huygens

Vector Vortex Beam Generation with a Single Plasmonic (a) The reflective-type half-wave plate consists of three layers:the ground gold layer (150 nm), the SiO 2 spacer layer (85 nm), and the top layer of gold nanorods (30 nm). Each pixel size is 300 nm by 300 nm. Each nanorod is 200 nm in length, 90 nm in width, and 30 nm in thickness.
