Quantum Control for Broadband Attosecond Pulse Generation
High harmonic generation Isolated attosecond pulse Two-color field
2009/6/1
Abstract: In our work, we propose a scheme for coherent control the HHG with an ultrashort laser pulse in combination with a controlling pulse. It is shown that this method can significantly modulate ...
High Efficiency and Broadband Microstrip Leaky-Wave Antenna
tapered design leaky-wave antenna an FDTD code
2010/12/6
A novel layout of leaky-wave antennas based on tapered design has been proposed and investigated. The new tapered leaky-wave antenna (LWA) was designed running a simple procedure which uses an FDTD co...
An E-field probe has been developed for EMC immunity tests performed in closed space. The leads are flexible resistive transmission lines. Their influence on the field distribution is negligible. The ...
Design of a Broadband Parallel-Coupled Microstrip Filters without Spurious Resonances
a Broadband Parallel-Coupled Microstrip Filters Spurious Resonances
2010/12/6
A design of parallel-coupled microstrip bandpass filters without spurious resonance is presented. Two different techniques are used to eliminate this response at twice the passband frequency (2fo). Th...
Development of Broadband Low Actuation Voltage RF MEM Switches
RF MEM space-based reconfigurable antenna integrated circuit applications
2010/12/7
Low insertion loss, high isolation RF MEM switches have been thought of as one of the most attractive devices for space-based reconfigurable antenna and integrated circuit applications. Many RF MEMS s...
Broadband Wireless Access With Optically Controlled Phased Array Antennas
Broadband Wireless Access Phased Array Antennas
2010/7/15
The rapid extension of communication requires systems having higher transmission capacity and lower infrastructure cost than is currently the case. For terrestrial communication, a very promising way ...
Broadband Waveguide Feed for Parabolic Reflectors
Broadband Waveguide Parabolic Reflectors
2010/12/15
The broadband requirement in microwave systems has necessitated attention on components that can operate over frequency ranges far broader than those of standard rectangular waveguides. This paper des...
