Influence of Material Properties on Rayleigh Critical‐Angle Reflectivity

This paper extends the investigation of critical‐angle phenomena and investigates the relationships between material properties and the condition (F0) for which zero reflectivity occurs. It was found that material attenuation, density, and velocity all influence F0. Graphs are presented for several materials from which the reader may determine F0 for a particular sample. Measurements which further verify the accuracy of the model, which we have used in these calculations, are also presented.
