WebOPTICAL / MIE / RAYLEIGH REGIONS Figure 7 shows the different regions applicable for computing the RCS of a sphere. The optical region (“far field” counterpart) rules apply when 2 ʌ r/ Ȝ > 10. In this region, the RCS of a sphere is independent of frequency. Here, the RCS of a sphere, ı = ʌ r 2. The RCS equation breaks down primarily due Websphere, the incident radiation is uniformly scattered in all directions (Isotropic scattering) and the RCS is given as, σπ=a2 When the wavelength is not small compared with the sphere radius, the calculation is much more complicated. This region where the wavelength is not small compared to the radius is called the Mie region or resonance region.
