The high reflection exhibited by the samples within visible spectral range can be attributed to the backscattering of the Ag NPs, which increases with the increased NPs' size.
For sample A, the longitudinal scan performed at the vicinity of the GaAs (022) reflection exhibits a much broader profile than the scan measured with the sample rotated by 90°, close to the G a A s ( 0 2 ¯ 2 ) reflection.
The light trapped in these resonators by means of total internal reflection exhibits very strong and sharp resonances, called whispering gallery modes (WGMs), at specific wavelengths known from Mie theory [2, 3].
The relatively large number of reflections exhibited by these systems is indicative of a para-crystalline order greater than that typically observed for amyloid-like systems [ 9].
The results for the transmission and reflection coefficients exhibit some previously unknown phenomena in the low fd regions of both zero order branches.
Experimentally, however, symmetric Bragg reflections were preferred as asymmetric reflections can exhibit complex absorption effects.
The measured reflection ratio exhibited the same trend as the simulation results between 800 MHz and 2.7 GHz.
As the grating period decreases from 1,040 to 1,020, the broad reflection band exhibits a distinct blue shift, indicating that the guided mode resonances shift proportionally to the grating period.
Consequently, the as-designed composites with flaky CIPs may exhibit reflection loss (RL) < −6 dB in 2.5 8 GHz and a minimum RL of −11 dB at 4 GHz when the thickness is 1.2 mm.
In addition, N12 and N44 exhibited reflection symmetry in the static stage during foam draining.
Graphite-coated FeNi nanoparticles exhibited reflection loss (RL) of approximately -23 dB with the thickness 2.5 mm and the absorption peak at 14 GHz [5].
