Compact, low-noise microwave sources are required throughout a wide range of application areas including frequency metrology, wireless-communications and airborne radar systems. And the photonic generation of microwaves using soliton microcombs offers a
Arid regions (B) have notable variability in product agreement (Table 3) as hot arid regions are minimally FT constrained (0.2–2.5% frozen) compared to cold arid regions (15.0–17.1%). The low frequency of FT transitions results in increased Ap over hot arid regions (97.4%) compared to ...
