TM scattering from a hollow slotted circular cylinder with thickness

TM scattering from a hollow, slotted, circular cylinder with thickness is investigated. The mode-matching technique (MMT) is used to express the scattered and guided fields in the angular spectral domain in terms of the radial waveguide mode. The boundary conditions are enforced on the conducting surface and the slot to obtain simultaneous equations. The simultaneous equations are solved to represent the fields in an analytic series form. The computed results are in very good agreement with other data. The numerical computations are performed to illustrate scattering behavior in terms of cylindrical geometry, incident angle, and frequency.
