A particle in a rectangular waveguide can be pulled towards the light source or pushed away from the light source just by varying the frequency around the waveguide cutoff frequency. All of the graphical representations and calculations are accurate within the Rayleigh scattering regime, but may be inappropriate for a larger particle.
Firstly, the CSRRs have extraordinary property of generating forward wave transmission below the waveguide cutoff frequency [11-16].
If D and the waveguide cutoff frequency [[omega].sub.c] are known exactly, the value of the coefficients [C.sub.0], [C.sub.1], [C.sub.2] and [C.sub.3] that specify the open circuit can be calculated as the Mac Laurin series of the capacitance vs.
This close spacing dictates dielectric loading to lower the waveguide cutoff frequency. Internal circular polarizers serve as these loads.
Figure 2 shows the computed coupling (all curves presented are normalized to the waveguide cutoff frequency) and pertinent coupler parameters.
The typical dielectric resonator filter consists of ceramic resonator discs mounted in a metal cavity operating well below its waveguide cutoff frequency. In this situation, the resonator basically behaves like a magnetic-walled waveguide, the dual of a waveguide cavity.
