Although the common usage in the literature for canonical scenarios is the field strength representation, in the following figures, we will use the relative attenuation
expressed in dB, because of its common use in real scenarios and measurements.
For the oriented nanocomposites with the maximum conductivity direction (LD) placed perpendicular to the E-field (90[degrees]), relative attenuation
of about 1.5 [+ or -] 0.6 dB and 5.3 [+ or -] 1.3 dB was measured for the PR-19 HT and MWNT HT-oriented nanocomposites, respectively (100 MHz to 2.5 GHz).

At 50 m, the maximum delay, considering a relative attenuation
of 10 dB referred to the strongest path, is 10-15 ns.
The differences in the mean sound pressure level resulted from the application of plants with different foliage types while the control group represented the relative attenuation
Thus, the relative attenuation
represents the decimal percentage that the actual signal fall-off is less than the standard fall-off i.e.
Most tests that exceed the capabilities of the Arb are relative attenuation
or gain of the input signal to the output.

of the ultrasonic signal through the thickness (center web) was measured using 500 kHz transducers and a high-temperature couplant as the specimen cooled from 121[degrees]C to room temperature.
6); conservatively assuming a 10% relative attenuation
, at distances greater than 4 cm, the loudest 832-Hz sounds were at least as loud as the loudest 72-Hz sounds.
% relative attenuation
= ([X.sub.NZ] - [X.sub.BS])*100/[X.sub.BS], (1)
So experimentally a relative attenuation
value ([a.sub.rel]) is measured to determine the E(t) function.
