A novel evanescent-mode filter structurebased on T- septum waveguide technology is presentedfor applications in extremelycompact designs. The excellent characteristicsof the. T-septum waveguide are utilized to significantly reduce the resonator cutoff frequency compared with standard ridge waveguide designs.
Abstract—Length reduction of evanescent-mode ridge waveguide bandpass filters is investigated extensively. Based on the conventional filter configuration, two new filter configurations are proposed: one is the generalized filter, and the other is the folded filter. In the generalized filter configuration, the cross sections of the

allows the placement of arbitrary numbers of ridges at arbitrary locations within a circular waveguide cross section and thus opens new possibilities for circular waveguide component design. Due to the reduction in cutoff frequency, the ridged cross sections are foremost employable in evanescent-mode-filters and offer a.
understanding and insight of the coupling mechanisms and the evanescent modes associated with the coupling, analytical dyadic Green's functions are employed. Two methods of field modulation are used in EPR. The first method is to slowly sweep the static magnetic field over the sample resonance line-width while a low
In more recent designs the screws are replaced with dielectric inserts. These capacitors resonate with the preceding length of evanescent mode waveguide which has the equivalent circuit of an inductor, thus producing a filtering action. Energy from many different evanescent
TM Modes. Consider the shape of the rectangular waveguide above with dimensions a and b (assume a>b) and the parameters e and m. For TM waves Hz = 0 and Ez should be solved from equation for TM mode;. N2xy Ez0 + h2 Ez0 = 0. Since Ez(x,y,z) = Ez0(x,y)e-gz, we get the following equation,. If we use the method of
