WebIn the Natural Units, the units of charge are defined by choosing ε0=1. This automatically sets μ0=1, since c2=1/(ε 0μ0). Since the units of force and distance in Natural Units are E 2 and 1/E, the electric charge turns out to be dimensionless in these units. The value of the fine structure constant, being dimensionless, is the same in all ...

WebThe natural units of the attenuation constant are Nepers/meter, but we often convert to dB/meter in microwave engineering. To get loss in dB/length, multiply Nepers/length by 8.686. Note that attenuation constant is always a positive number, if it was negative you'd violate the First Law of Thermodymamics (you never get something for nothing!)

ISO 80000-3 describes definitions for quantities and units of space and time. The IEC Standard 60027-3:2002 defines the following quantities. The decibel (dB) is one-tenth of a bel: 1 dB = 0.1 B. The bel (B) is 1⁄2 ln(10) nepers: 1 B = 1⁄2 ln(10) Np. The neper is the change in the level of a root-power quantity when the root-power quantity changes by a factor of e, that is 1 Np = ln(e) = 1, thereby relating all of the units as nondimensional natural log of root-power-quantity r…
