IEEE Microwave Theory and Techniques Society
The IEEE MTT-S Logo
The IEEE Microwave Theory and Techniques Society (MTT-S) is the largest technical profession society for the promotion of the theory and applications of RF, microwave, millimeter-wave, and terahertz technologies. The MTT-S has over 11,000 worldwide professional members in academia, industry and government laboratories. It was founded in 1952 and has over 170 local chapters. MTT-S is one of 45 technical societies and councils of the IEEE.
Field of Interest
The MTT-S’ field of interest is "microwave theory, techniques and applications" of RF, microwave, guided wave, and wireless technologies, as they relate to components, devices, circuits, transmission lines, and systems involving the generation, modulation, demodulation, control, transmission, detection and effects of electromagnetic signals. It shall include scientific, technical, and industrial activities. MTT-S members apply physical and mathematical principles to design, analyze and build structures with dimensions representing a significant fraction of a wavelength or when propagation effects need to be considered.
