要約

The classic solution is exploited of the plane wave diffraction by a circular metallic cylinder. The spatial field distribution was constructed for four characteristic frequencies. The lower couple of them corresponds to the first maximum and minimum in the complete field observed at the rear of the cylinder. Two higher frequencies, around 100 GHz, are related to the field maximum and minimum at the same point. Angular patterns of the scattered and full field are constructed. The effect is discussed similar to the Gibbs phenomenon arising in the Fourier expansion of a «square» wave. In the 2D case, the effect vanishes when the number of terms in the field expansion exceeds a threshold that depends on the relation between the radius of the scatterer and the incident wavelength.
