The phase shift of a propagating mode in such switching devices will be studied in two cases: neglecting absorption loss
and including absorption loss
; The phase shift of a propagating mode in a lossless waveguide can be expressed as
The insertion loss (transmission) and absorption loss
of barium niobate sample were measured by the rectangular waveguide reflectometer setup shown in Figure 6.
A dangling bond at the grain boundary causes absorption loss
that contributes significantly to transmission loss.
Meanwhile, the overall absorption loss
of the SRR metamaterial enhances.
Such wide absorption widths and high absorption loss
peaks indicate that it has wide application as microwave absorbing material.
where R and A are the reflection loss and the absorption loss
in decibel (dB), respectively.
We hope to develop food products that have benefits in terms of reducing fat absorption loss
in tasty products people want to eat," he said.
can be enhanced using absorber materials inside the enclosure.
The effective mode indices values for the proposed fiber at different wavelengths are obtained using the simulation results and the absorption loss
values are calculated  using the expression, [alpha] = 8.
where B is a term which take into account the loss caused by multiplereflection inside the shield, R is the reflection loss, and A is the absorption loss
Conventional polycarbonate is one type of excellent polymer materials in the visible wavebands (400-700 nm), but its application in optical communication devices is limited because of its high absorption loss
characteristic in the infrared waveband (11).
R = total reflection loss * A = total absorption loss
, and * B = re-reflection loss.
