Abstract :
The rigorous solution of the problem is given. The boundary-value method using the property of completeness of angular functions on the certain interval is employed to obtain the solution. Accurate numerical results are presented in the case of H-polarized waves. Diffracted far-field (DFF) and back radar cross section (BRCS) of the structure are evaluated asymptotically. It is shown that in the low-frequency region there is resonant penetration of an electromagnetic field inside the cylinder at a narrow slot. In this case, the BRCS of the structure is greatest and the form of the DFF pattern is close to circular
