关于双曲型方程剑桥经典书籍!好东西分享! Hyperbolic conservation laws describe a number of interesting physical problems in diverse areas such as fluid dynamics, solid mechanics, and astrophysics. Our emphasis in this book is on nonlinearities in these problems, especi
This book is a somewhat revised version of notes from lectures giyen at the University of Lund during three semesters 1986-87. The aim of those lectures was to present the main results then known about global existence or "blowup" of solutions of non
Bound States for Spin-0 and Spin-1/2 Particles with Vector and Scalar Hyperbolic Tangent and Cotangent Potentials,田文杰,,This paper analyzes the relativistic bound states with the direct coupling of a vector and a scalar hyperbolic tangent or cotangent
A theoretical model of a nonlinear hyperbolic metamaterial is presented in the form of a stack of subwavelength layers of linear plasmonic and nonlinear dielectric materials. A broad picture of the properties of evanescent waves (high-k modes) in thi
We have studied a switchable hyperbolic metamaterial composed of a graphene–dielectric periodic structure. By tuning the chemical potential of all graphene sheets simultaneously, the isofrequency curve can switch between an ellipse and a hyperbola co
