Vue de la rade depuis les terrasses du quartier asiatique du City Center.

There is described herein an active bidirectional tag for use in an RF signaling system for real-time and non-real time localization. The tag has a first antenna that...

Technological advances in the field of integration of functions in silicon technologies and their miniaturization have allowed the development smart electronic devices...

Within the wireless digital communication framework, data exchange speed (throughput) still remains as one of the characteristics that limits the system performance....

Chipless RFID tags, owing to their low cost, have opened a new way to the identification systems. Chipless RFID tags operating in the time domain have the advantage of...

Reconfigurable antennas offer multiple functions by dynamically changing their properties such as operating frequency, polarization, radiation pattern, and a...

This paper deals with the analysis of the transient disturbances produced above of a train due to the pantograph-catenary power supply system. The goal is to study the...
