An Analytic Design Method Of Scattering Field Intensity Shaping Based On All-Dielectric Cylinders

It is an interesting function to obtain the desired distribution of scattering field intensity in the target areas. In this paper, we propose an analytic design method for scattering field intensity shaping with all-dielectric cylinders. Based on the spatial Fourier angular transform and the concept of induced source, we inversely design scattering structure distribution and obtain the electromagnetic parameter values by analytical calculation from the desired distribution of the scattering field intensity at the target area. The Sinc-shape and triangular-shape scattering field intensity distributions expected in the target area are taken as examples for full-wave simulation experiments. The satisfactory results show the effectiveness and reliability of the proposed reverse design method.
