ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. we...

The paper presents the results of 3D FDTD modeling of a 915 MHz cylindrical structure with a spherical load (fruit). Three different configurations of the loops exciting the TM01l mode are analyzed. The coupling is shown not to be sensitive to the load’s temperature and to the type of the fruit.

We present an infrared adaptation of the Cluster Red-Sequence method. We modify the two filter technique of Gladders & Yee (2000) to identify clusters based on their R − [3.6] color. We apply the technique to the 4 degree Spitzer First Look Survey and detect 123 clusters spanning the redshift range 0.09 < z < 1.4. Our results demonstrate that the Spitzer Space Telescope will play an important r...
