Introduction

Abstract

Transparent materials form a special group of materials that have a wide range of applications in various aspects of our daily life. Transparency, also known as pellucidity or diaphaneity, is a unique physical property of materials, which measures their ability to allow light to pass through them without the presence of scattering. At macroscopic scale, the behavior of the photons follows Snell’s law, because this dimension is much larger than the wavelength of photons. Translucency is another property closely related to transparency, which is also known as translucence or translucidity.
