This book explores the complex geometry of radiating surfaces, delving into the fundamental principles that govern how they emit and distribute light. The author, a renowned scientist, meticulously analyzes the behavior of various radiating sources, from point sources to complex shapes like cylinders and strips. By deriving mathematical equations and conducting numerical computations, this book uncovers the intricacies of light distribution and its dependence on distance and angle of emission. It challenges the widely accepted inverse square law and cosine law, demonstrating the limitations of these approximations when applied to real-world radiating surfaces. Through rigorous analysis, the author reveals the significant deviations that occur, particularly in close proximity to extended sources. The book's insights are invaluable for researchers and practitioners in optics, illuminating engineering, and other fields that involve the study and application of light. It provides a comprehensive understanding of the geometrical factors influencing light propagation, enabling more accurate modeling and optimization of lighting systems.

Excerpt from Geometry Theory of Radiating Surfaces With Discussion of Light Tubes
Thus the intensity of illumination due to an infinitely long uni formly radiating cylinder varies inversely as the first power of the distance from the axis of the cylinder, a result which also follows from purely physical considerations of the normal flow of energy across coaxial cylindrical surfaces.
