Decam is a research area that focuses on the study of the decameter wavelengths of electromagnetic radiation, which fall within the frequency range of approximately 10 to 100 meters. Decam research encompasses a wide range of disciplines, including radio astronomy, communications, and atmospheric science. Researchers in this area typically study the propagation, polarization, and interaction of decameter waves with various mediums and environments. Decam research is important for understanding the behavior of electromagnetic radiation in different contexts and for developing applications in fields such as remote sensing, radar, and space exploration.
