The IEEE Transactions on Antennas & Propagation publishes full papers and shorter Communications on original contributions within the general topics of electromagnetics, antennas and wave propagation. Specifically the journal focuses on: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
