Shielding properties of thin curved surfaces

Electromagnetic propagation through curved surface is important in the area of shielding for the design of the proper shield. The radar cross section is the only important parameter in determining the electromagnetic shielding properties of surfaces. The radar cross sections of a dielectric thin curved surface are obtained by employing a quasi-static approximation. The results are complemented by numerical calculations and their validity are presented by comparison with available exact results in literature. Excellent agreement is found for horizontal and vertical polarization.
