Abstract: Our insight into the structural properties of cosmic dust has been improved by observations at higher spectral resolution and in a wider range of wavelengths. However, the formation and processing of main dust components in different astrophysical environments is not yet completely understood. Laboratory experiments combined with structural analyses are necessary to get more insight into the formation pathways and chemical-structural modification of solid grains in different astrophysical environments. Spectroscopy is a main tool to characterize dust analog materials and to monitor ongoing structural transformations, but provides also the major link to astronomical observations and the tool for identification of cosmic dust properties. We review recent laboratory work on cosmic dust analogs, highlighting modern condensation experiments and studies of thermal processing, UV and ion irradiation which have considerably improved our understanding of cosmic dust formation and processing in space. In addition, we demonstrate the progress in spectroscopic studies, which have recently widened the spectroscopic database available to modelers and observers, especially at extreme wavelengths and for dust at low temperature.
