It is proved that the attenuation of an acoustic wave brings about a decrease in the diffraction efficiency and an increase in the transmission bandwidth of the device used.
It is shown that electronic restructuring of not only the central transmission frequency but also the transmission bandwidth of the filter as well as the form of the transmission curve is possible in collinear acousto-optic filters.
We show a significant improvement in both the transmission efficiency (up to 97%) and the transmission bandwidth by performing an optimization based on a sensitivity analysis.
By employing the method of the separation of variables in the circular-cylindrical system,a recursive formula for the electromagnetic fields in the metal coaxial line filled with multi-layer reciprocal chiral media is derived.The general mode eigenequation is given.In the same way the eigenequation for the metal circular waveguide filled with multi-layer reciprocal chiral media can also be obtained.From the general eigenequations of the metal coaxial line and the metal circular waveguide filled with multi-l...
