Electromagnetic sensing is a field of research that focuses on using electromagnetic signals to detect and analyze various properties of objects or environments. This technology utilizes electromagnetic waves, such as radio waves, microwaves, or infrared radiation, to gather information about the composition, shape, size, distance, or movement of objects. Electromagnetic sensing has applications in a wide range of fields, including remote sensing, environmental monitoring, medical diagnostics, and security systems. Researchers in this area develop sensors, imaging systems, and data processing techniques to extract valuable information from electromagnetic signals for different purposes.
