reflection loss

[ri′flek·shən ‚lȯs]
(electricity)
Reciprocal of the ratio, expressed in decibels, of the scalar values of the volt-amperes delivered to the load to the volt-amperes that would be delivered to a load of the same impedance as the source.
Apparent transmission loss of a line which results from a portion of the energy being reflected toward the source due to a discontinuity in the transmission line.

The reflection loss (RL) of composite nanofibers was calculated by Matlab based on the relatively complex permeability and permittivity at a given frequency and matching thickness according to the following equations:
In our best design, nearly two-thirds of the surface can be covered with metal, yet the reflection loss is only 3 percent.
In addition, better than 10dB reflection loss is realized every time at the resonant frequency as shown in Fig.
In order to reduce the reflection loss without the additional processing steps required for coating the backside of the grating facets with a reflecting metal, a total internal reflection (TIR) V-shaped facet was used at each grating tooth (see Figure 1(d)).
An additional correction for end reflection loss (ERL) must also be added to discharge sound levels for air terminals.
lower values of reflection loss, was observed for the case of RHC absorber, while, conversely, the performance of the RTC absorber decreased.
64dB and reflection loss is better than 20 dB in the passband.
The drops at the lower frequencies correspond to the end reflection loss that is most pronounced for small ducts at low frequencies.
Taking into account the different sizes of the Ti- and Be-traps we find no difference in the reflection loss coefficient for the two kinds of sub-layer.

Lehigh measured an average connector reflection loss of 28dB.
