Time domain radiation and absorption by subwavelength sources
Time domain radiation absorption subwavelength sources elementary sources
2011/8/5
Abstract: Radiation by elementary sources is a basic problem in wave physics. Although computations of radiated fields in the time domain are textbook examples, the emitted energy flux is usually comp...
Persistent junk solutions in time-domain modeling of extreme mass ratio binaries
extreme mass ratio binar time-domain modeling
2010/3/17
In the context of metric perturbation theory for non-spinning black holes, extreme mass ratio binary (EMRB) systems are described by distributionally forced master wave equations. Numerical solution o...
Finite Difference-Time Domain solution of Dirac equation and the Klein Paradox
finite difference time domain(FDTD) Dirac equation numerical solution wave packet Klein paradox
2010/4/9
The time-dependent Dirac equation is solved using the three-dimensional Finite Difference-Time Domain (FDTD) method. The dynamics of the electron wave packet in a scalar potential is studied in the ar...
