An optimal reflection loss of −41.1 dB is reached at 8.2 GHz with a matching thickness of 2.2 mm, the bandwidth with a reflection loss less than −10 dB is obtained in the 5.5 11.3 GHz range for absorber thicknesses of 1.5 2.5 mm.
The optimal reflection loss (RL) of Fe@C@BaTiO3-parrafin composites are −40.2 dB at 8.14 GHz with a thickness of 2.24 mm and the absorption bandwidth of those below −10 dB is 8.4 GHz with only absorbent thicknesses of 1.7 2.0 mm.
The optimal reflection loss (RL) of Ni@BaTiO3-parrafin composites are −42.3 dB at 10.6 GHz with an absorbent thickness of 1.88 mm and the absorption bandwidth of those below −10 dB is 6.75 GHz only with absorbent thicknesses of 1.7 2.5 mm.
The optimal reflection angle was determined by means of optical simulation.
Furthermore, via adjusting the thickness to only 1.65 mm, the optimal reflection loss can obtain −51.2 dB at 13.92 GHz with a broad bandwidth of 4.4 GHz.
Optimal low reflection of the microwave radiation was achieved using the three-stub tuner.
First, the proportion of patients in whom the observed optimum was a correct reflection of the underlying true optimal AV delay.
Evidently, these technical improvements mystify the practice of neuroradiology and request a constant reflection of the optimal combination of imaging parameters.
Therefore, per-visit measures gave a better reflection of average and optimal adherence than per-participant measures.
An optimal stacking arrangement allows, in principle, the reflection of all neutrons incident on the lens within the appropriate angular divergence range.
