Book Description
Discover the most recent advances in electromagnetic vortices In Electromagnetic Vortices: Wave Phenomena and Engineering Applications, a team of distinguished researchers delivers a cutting-edge treatment of electromagnetic vortex waves, including their theoretical foundation, related wave properties, and several potentially transformative applications. The book is divided into three parts. The editors first include resources that describe the generation, sorting, and manipulation of vortex waves, as well as descriptions of interesting wave behavior in the infrared and optical regimes with custom-designed nanostructures. They then discuss the generation, multiplexing, and propagation of vortex waves at the microwave and millimeter-wave frequencies. Finally, the selected contributions discuss several representative practical applications of vortex waves from a system perspective. With coverage that incorporates demonstration examples from a wide range of related sub-areas, this essential edited volume also offers: Thorough introductions to the generation of optical vortex beams and transformation optical vortex wave synthesizers Comprehensive explorations of millimeter-wave metasurfaces for high-capacity and broadband generation of vector vortex beams, as well as orbital angular momentum (OAM) detection and its observation in second harmonic generations Practical discussions of microwave SPP circuits and coding metasurfaces for vortex beam generation and OAM-based structured radio beams and their applications In-depth examinations and explorations of OAM multiplexing for wireless communications, wireless power transmission, as well as quantum communications and simulations Perfect for students of wireless communications, antenna/RF design, optical communications, and nanophotonics, Electromagnetic Vortices: Wave Phenomena and Engineering Applications is also an indispensable resource for researchers in academia, at large defense contractors, and in government labs.

Book Description
This timely anthology examines the use of drones by the military, law enforcement, border patrol, and civilians. Articles condoning the use of drones in military engagements abroad are balanced with reportage of civilian deaths and resulting creation of more terrorists. Pieces touting the effectiveness of drones in domestic surveillance are countered by assertions that they violate Americans’ civil liberties. Opinions about the pros and cons of drone use in securing our borders, as well as the potential benefits and dangers of their commercial use, will add to readers’ deep understanding of this complex issue.

Book Description
In this revision: The electric charge of a subatomic particle is originated from its Orbital Angular Momentum (OAM). The electron mass is a magnitude that expresses quantitatively the square of its magnetic flux quantum. The proton, the neutron and all baryons consist of three energy levels on which the quarks are orbiting. The third energy level is equivalent to 80.5 Gev; it plays a role at decaying process through the weak force. The quark's OAM is a third or two thirds of the reduced Planck constant. The proton's missing spin is resolved by quarks OAM contribution. The electron is a bound state composition of a negative Pion and an electron Neutrino. The theory predicts a neutral boson of 160Gev (alongside to W+ boson from a 240Gev decaying particle). The 2007 data analysis at CDF (Tevatron) showed this possibility. Apparently this was a valid finding despite the final results.The 240Gev particle can also decay to two W+ and one W- Bosons instead of 160Gev Boson which makes it hard to be detected.
