We report experimental results of using an f/5 , cascaded-focus optical geometry for a high-dynamic-range optical limiter. The device consists of a 2-cm-thick CS(2) cell at the first focus and a reverse saturable-absorber dye in a thin cell (0.1 mm) at the second focus. The strong self-focusing in the CS(2) that is due to the ac Kerr effect and electrostriction keeps the energy at the second ce...

We propose a high order finite difference linear scheme combined with bound preserving maximum-principle-preserving (MPP) flux limiter to solve the incompressible flow system. For such problem highly oscillatory structure but not strong shocks, our approach seems be less dissipative and much costly than WENO type scheme, has resolution due Hermite reconstruction. Spurious numerical oscillations...
