| Abstract: | With the use of the 1D wave equation as an example, the wave incidence on one interface and on two interfaces of media with arbitrary complex parameters is analyzed. It is noted that, when the energy reflection, transmission, and absorption coefficients are calculated by means of traditional techniques, their sum exceeds unity if the wave number in the first medium is complex. The complex character of the energy balance on the media interfaces is revealed. Definitions are introduced and the properties of complex reflection, transmission, localization, reactivity, and absorption are considered. |
