Wire grid modelling of cylinder

[vineethajoy]

Hi,

I was trying to model a finite PEC cylinder parallel to the Y axis. The diameter of the cylinder is
chosen to be one wavelength, and the height is 1.5 wavelengths. The object is illuminated by a plane
wave propagating in the z direction and E-polarized in the x direction ( Reference attached). The input file I wrote is given below:

CM RCS of PEC Cylinder
CM F=100MHz, Radius=1.5m, Height=4.5m, seg. length=0.25m, seg. radius=0.02m
CM Tag.number 1's=For bottom and top face
CM Tag.number 2's=For side face
CM Tag.number 3=For top face extreme radial arc

I am stuck with the modelling of top and bottom faces as they are getting segment errors. Can someone help me with this.
