Abstract : The theory of the scattering of electromagnetic radiation in the transverse magnetic mode by infinite plasma cylinders with radially varying electron-density distributions is reviewed. Techniques for calculating the scattering cross section are described, with special emphasis placed on short wavelength scattering. Specific calcu lations of the back-scattering (radar) cross section are made in the geometrical-optics limit and in the Born-approximation limit for several monotonically decreasing electron-density distributions which have zero slope on the cylinder axis. The radar cross section in the region of transition from underdense to overdense plasma is programmed and computed on the IBM 7090 for a Gaussian and for a quadratic electron distribution for wavelengths equal to 1/10 and 1/100 of the cylinder radius.
