"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 ... " - Natural units to db

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!) WebAlso, whatever units you prefer to use for wavelength will be preserved in the loss calculation, so if you enter wavelength in centimeters, the loss will come out in Nepers/centimeter. In order to arrive at the "more engineeringly" units of decibels/meter, we note that one Neper is 8.68588 dB (exactly 20/ln(10)), and pi=3.14159, then we simplify:
