文摘

To solve the problem related to scattering by a perfectly conducting thin cylinder, approximate approach was developed based on use of Pattern Equation Method (PEM). Explicit formulas were obtained for total scattering cross-section applicable for cylindric scatterers of complex shape. It is shown that calculation accuracy controlled by calculating the balance of power flows for incident and scattered waves (checking the accomplishment of optical theorem) is quite sufficient for practice.
