9781390391633 - An Electromagnetic Formulation for Treating Optical Reflections From Graded-Material Surfaces (Classic Reprint) de Lieberman, Alfred George (1 resultados)

Paperback. Condición: New. Print on Demand. This book introduces a ground-breaking method for applying electromagnetic principles to analyze optical reflections from surfaces with varying material compositions. The author derives a non-linear differential equation that the reflection coefficient for either linear polarization of light must obey. This approach allows for the direct computation of reflection coefficients without the need to tediously solve complex Maxwell's equations. An alternative formulation using wave impedance and admittance is also explored, revealing a bilinear transformation that links it to the reflection coefficient formulation. The book emphasizes that both formulations can be applied even to reflections from the surfaces of metals, a previously insurmountable obstacle. The author demonstrates how the wave admittance formulation can be particularly useful for eliminating the appearance of singularities that hinder the reflection coefficient formulation. Overall, this book offers a robust and innovative set of tools for understanding and analyzing optical reflections, making it an important resource for researchers and practitioners in optics and related fields.
