We choose the monitoring signal as 1625nm wavelength from U-band in order to avoid interference with traffic at 1310 and around 1550 nm.
Thus, we can add another wavelength (1625 nm) from U-band as we proposed before by using a technique known as wavelength division multiplexing (WDM).
11[delta]] [7] lies in the U-band (40-60 GHz), whereas for the smaller disk (Sample B) has the resonance in the W-band (75-110GHz).
The scattering matrix element measurements were made using Agilent Network Analyzers (model E8361A for U-band and N5242A with N5260A for W-band).
Frequencies of these modes lie in the U-band, well above the FMR frequency of 1-5 GHz for the biasing fields for the profiles in Fig.
From this consideration it is clear that for U-band the operating point is ideally around 55.
The phase shifter discussed here has a figure-of-merit (FOM), approximately 25[degrees]/dB at U-band and 19[degrees]/dB at W-band.
Field tests show that the DSI Pro has excellent blue response (I was able to get images through an ultraviolet U-band filter).

In studying the structure of sunspots, notes the VLA's Tim Bastian, the facility heretofore listened primarily to the 2-cm radio waves of what is called the U-band, originating near the bottom of the chromosphere, and to the 6-cm (C-band) emissions from the top.
The Purdue team of five students, led by Professor Byunghoo Jung and his assistant team leader, Professor Dimitrious Peroulis, placed first in both Phase 1 and 2 for their entry, "Chip-to-chip Wireless Data Link using U-band Transceiver.
