Ion acceleration and extreme light field generation based on ultra-short and ultra–intense lasers

By: Liangliang Ji

This book is dedicated to the relativistic (laser intensity above 1018 W/cm2) laser-plasma interactions, which mainly concerns two important aspects: ion acceleration and extreme-light-field (ELF). Based on the ultra-intense and ultra–short CP lasers, this book proposes a new method that significantly improves the efficiency of heavy-ion acceleration, and deals with the critical thickness issues of light pressure acceleration. More importantly, a series of plasma approaches for producing ELFs, such as the relativistic single-cycle laser pulse, the intense broad-spectrum chirped laser pulse and the ultra-intense isolated attosecond (10-18s) pulse are introduced. This book illustrates that plasma not only affords a tremendous accelerating gradient for ion acceleration but also serves as a novel medium for ELF generation, and hence has the potential of plasma-based optics, which have a great advantage on the light intensity due to the absence of device damage threshold.

The Inclusion-Based Boundary Element Method (iBEM)

By: Huiming Yin,Gan Song,Liangliang Zhang,Chunlin Wu

The Inclusion-Based Boundary Element Method (iBEM) is an innovative numerical method for the study of the multi-physical and mechanical behaviour of composite materials, linear elasticity, potential flow or Stokes fluid dynamics. It combines the basic ideas of Eshelby's Equivalent Inclusion Method (EIM) in classic micromechanics and the Boundary Element Method (BEM) in computational mechanics. The book starts by explaining the application and extension of the EIM from elastic problems to the Stokes fluid, and potential flow problems for a multiphase material system in the infinite domain. It also shows how switching the Green's function for infinite domain solutions to semi-infinite domain solutions allows this method to solve semi-infinite domain problems. A thorough examination of particle-particle interaction and particle-boundary interaction exposes the limitation of the classic micromechanics based on Eshelby's solution for one particle embedded in the infinite domain, and demonstrates the necessity to consider the particle interactions and boundary effects for a composite containing a fairly high volume fraction of the dispersed materials. Starting by covering the fundamentals required to understand the method and going on to describe everything needed to apply it to a variety of practical contexts, this book is the ideal guide to this innovative numerical method for students, researchers, and engineers. - The multidisciplinary approach used in this book, drawing on computational methods as well as micromechanics, helps to produce a computationally efficient solution to the multi-inclusion problem - The iBEM can serve as an efficient tool to conduct virtual experiments for composite materials with various geometry and boundary or loading conditions - Includes case studies with detailed examples of numerical implementation

Multibeam Phased Array Antennas as Satellite Constellation Ground Station

By: Guolong He,Xin Gao,Rentian Zhang,Liangliang Sun,Hui Zhou

This book focuses on the multi-beam phased array antenna as a satellite ground station. As there are already many excellent books on phased array antennas in the literature, this book focuses mainly on some engineering practices and fills the gap between principles and practices, such as array excitation error impact analysis and calibration methods, array geometry design for hemispherical coverage, multiple beam resource management, etc. This book is particularly suitable for readers interested in satellite constellation design or satellite ground station design. This book also benefits researchers and engineers in the fields of phased array antennas, aerospace engineering, telecommunications, etc.
