eikonal equation如下:|∇xτ(x)|=n(x).|∇xτ(x)|=n(x).定义Hamiltonian:H(p,x)=12n−2(x)|p|2−12H(p,x)=12n−2(x)|p|2−12,于是可得0=dH=∑j∂H∂pjdpj+∑j∂H∂xjdxj.0=dH=∑j∂H∂pjdpj+∑j∂H∂xjdxj. 若我们参数化x和p,令dxj(t)dt=∂H∂...
The Eikonal equation is defined as an equation on a computational domain where the gradient of a function is equal to a given function, with boundary values prescribed on the boundary of the domain. It is used to propagate information from the boundary to the rest of the domain through a se...

什么是Eikonal Equation(程函方程)? 程函方程最起初是描述波的传播的一个偏微分方程. 它表示波在传播过程中以一定的速度传播,这个速度可以在不同位置有所不同,根据介质或环境的性质而变化。 程函方程的一般形式如下: |∂D(x)|=F(x) D(x): 这是Eikonal方程的未知函数,通常被称为程函或距离场。D(x)表示从...

We derive the eikonal equation of light wavefront in the presence of Lorentz invariance violation (LIV) from the photon sector of the standard model extension (SME). The results obtained from the equations of the E and B fields, respectively, are the same. This guarantees the self-consistency...
