[ \sigma = \frac4\pi A^2\lambda^2 \left[ \frac\sin(kL\sin\theta)kL\sin\theta \right]^2 \cos^2\theta ]
This is the holy grail chapter. Knott explains how ferrite-loaded paints, Dallenbach layers, and Jaumann absorbers work. If you are searching for the PDF, it is likely for this section—the physics of converting radar energy into heat. radar cross section eugene f. knott pdf
If you are a U.S. government employee or contractor with a .mil email, check DTIC. RADC-TR-80-259 (the precursor to the book) is often available for unrestricted distribution. It is not as polished as the Artech book, but it contains Knott’s raw genius. radar cross section eugene f. knott pdf
