We deduce a complete wave propagation equation that includes inhomogeneity of the dielectric constant and present this propagation equation in compact vector form. Although similar equations are known in narrow fields such as radio wave propagation in the
Digital radiography (DR) and whole-body fluorescent optical imaging (WFOI) have been widely applied in the field of molecular imaging, with the advantages in tissues and functional imaging. The integration of them contributes to the development and discov
The current and potential applications of reststrahlen bands in optical surfaces and components are reviewed. This type of interval with metallic-like high reflectance has been used for monochromatization in infrared and when wavelength-selective low emit
