Graphene Enables Tunable Microwave Antenna

2015-05-26 08:48:55| wirelessdesignonline News Articles

Graphene antennae in the microwave part of the spectrum can be tuned by an applied voltage. This is the latest result, published in the renown physics journal Applied Physics Letters, by a pan-European collaboration between Romania, Greece, Italy, and Ireland, using Graphenea graphene.By Marko Spasenovic

Tunable Laser Source offers sub-picometer tuning repeatability.

2015-03-27 13:31:08| Industrial Newsroom - All News for Today

As module for 8164B lightwave measurement system, 81606A accelerates automated adjustment of wavelength-selective devices to facilitate device verification. Respective tuning ranges for Option 216 and 116 are 1,450–1,650 nm and 1,490–1,640 nm. While cavity and laser module design promotes dynamic range, wavelength reference unit maximizes accuracy. Feedback controls and drive mechanics enable accelerated sweeps without impacting specified dynamic accuracy.
