The propagation of two femtosecond pulses in the region with minimum group-velocity dispersion,influenced by the crossphase modulation(XPM) in photonic crystal
Reflection filters have various applications in optical communication and other systems.In this letter,we propose a narrowband high-reflection filter composed o
This paper presents an improved analytical model for an RF-LDMOST structure based on the 2D Poisson equation.The derived model indicates the influence of high d
A 264 MHz CMOS 4th G_m-C LPF target for the UWB standard is presented.The filter is designed by cascading two biquad cells.Compared with the previously publishe
The vertical structure of the crustal block of the Songliao Basin can be divided into upper, middle and low Earth’s crust according to density. There is an abo
