MTT-S Logo-blue-WebHex The MTT-S is a transnational society with more than 10,500 members and 190 chapters worldwide. Our society promotes the advancement of microwave theory and its applications, including RF, microwave, millimeter-wave, and terahertz technologies.

For more than 60 years the MTT-S has worked to advance the professional standing of its members and enhance the quality of life for all people through the development and application of microwave technology. As we enter into an exciting future, our mission is to continue to understand and influence microwave technology, and to provide a forum for all microwave engineers. The MTT-S will continue to be the global focus for promotion of the RF and microwave engineering profession, by advancing and distributing knowledge and supporting professional development.

This is an all-volunteer society, driven to excellence by its leadership, with the active participation of all its world-wide members. The activities sponsored by the MTT-S include a broad spectrum of conferences, workshops, tutorials, technical committees, chapter meetings, publications and professional education programs. Our principal publications and conferences are world class, peer reviewed and recognized as top of class. Our professional venues provide a great opportunity for networking with experienced innovators, experts, and practitioners. Our volunteer programs provide for the development of critical, non-technical skills that enable you to be more effective professionally.

The MTT-S publishes peer-reviewed technical papers in the Transactions on Microwave Theory and Techniques, the Transactions on Terahertz Science Technology, the Microwave and Wireless Component Letters, and the Microwave Magazine.

aps logo The AP-S's core purpose is to foster antennas, propagation and electromagnetics theory, technology, and applications innovation and excellence for the benefit of humanity. The Society membership ranged between 8700 and 9000 in the last six years.

The field of interest of the Society includes: antennas, including analysis, design, development, measurement, standards 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 at all frequencies.

AP-S will be essential to the global electromagnetics community, and be universally recognized for the contributions of antennas, propagation, and electromagnetics and its professionals in improving worldwide conditions.
