Hyperfine Interaction, Zeeman and Stark Effects for Excited States in Cesium

Our previous measurements in the P and D series in 133 Cs have been extended to a number of higher lying levels, populated in a two-step excitation process involving an rf lamp and a CW dye laser. The D states were studied with the level-crossing technique, while the optical-double-resonance method was used for the investigation of the P states. For the magnetic dipole interaction constant a , the

System and Method for Controlling Motion of Spacecrafts

A motion of an object is controlled from a geostationary transit orbit (GTO) of an earth to an orbit of a moon. A first trajectory of the motion of the object is determined from an intermediate orbit of an earth to a neighborhood of a stable manifold of a first Lagrange point (L1). A second trajectory of the motion of the object is determined from the GTO to the intermediate orbit. A third traject

Enhancement of VCO Linearity and Phase Noise by Implementing Frequency Locked Loop

This paper investigates the on-chip implementation of a frequency locked loop (FLL) over a VCO that decreases the phase noise and linearizes the transfer function. Implementation of the FLL inside a PLL is also investigated and a possible application is highlighted. Design of a special kind of low noise frequency detector without a reference frequency (frequency-to-voltage converter), which is the

Reconstruction of bi-isotropic material parameters using transient electromagnetic fields

In this article, a non-iterative method for solving the transient electromagnetic inverse scattering problem for a homogeneous, dispersive bi-isotropic slab is considered. The slab is excited by a normally incident transverse pulse. The inverse scattering problem is to determine (finite time traces of) the susceptibility kernels, i.e., the four integral kernels present in the constitutive relation

A Compressed Depth Cache

We propose a depth cache that keeps the depth data in compressed format, when possible. Compared to previous work, this requires a more flexible cache implementation, where a tile may occupy a variable number of cache lines depending on whether it can be compressed or not. The advantage of this is that the effective cache size increases proportionally to the compression ratio. We show that the dep
