From June 28 to July 2, 2021 in the village of Divnomorskoye, the face-to-face International Scientific Conference "Radiation and Scattering of Electromagnetic Waves" (RSEMW'21) was held. The conference dates back to 1999 and is held every two years in Gelendzhik Bay on the Black Sea coast. For the first time, our laboratory organized within the framework of this Conference a new separate thematic section on the theory of transport and scattering of light in turbid media as applied to the problems of biomedical optics. On medical topics, 6 oral section reports, two poster reports and one plenary report were presented at the Conference. Conference materials published in IEEE Хplore : https://ieeexplore.ieee.org/xpl
