Abstract :
The effect of the acceleration on the signal scattered by a rotating, perfectly electrically conducting cylinder is investigated. This problem is discussed in terms of the Franklin transformation. However, the scattering of electromagnetic plane waves by a conducting cylinder in uniform rotation were investigated by many researchers in the past by using Galilean rotation. These discussions show that the effect of rotation is negligible in the case of a perfectly conducting cylinder. In this paper, we use the Franklin transformation to analyse the scattering of both types of electromagnetic waves (H-wave and E-wave) by a rotating circular very good conductor cylinder for a small angular velocity and we show that the rotation of a very good conducting cylinder generates a distortion that is evident on the scattering patterns. This distortion is more evident in the case of an incident time-harmonic plane H-wave (TE-mode). The results indicate that the magnitude and phase of the backscattered field of an H-wave by a rotating very good conducting cylinder is different from stationary one.
