The ElectroMagnetics Academy (TEMA), founded by the late Professor Jin Au Kong (1942 - 2008) at MIT on 3 May 1989, is a nonprofit educational institution registered in the Commonwealth of Massachusetts, USA. TEMA is governed by a Board of Directors and operated by an Executive Committee consisting of the President, Vice President, Director of Operations, and Chairs of Committees.

TEMA is committed to academic excellence and the advancement of research and applications in electromagnetic theory, while also supporting the educational objectives of the electromagnetics profession. With the vision of "Advancing Photonics and Electromagnetics Science and Technology Without Borders for the Benefit of Humanity," TEMA aims to propel scientific and technological progress, nurture the next generation of leaders, and recognize those who contribute to advancements in photonics and electromagnetics

TEMA fosters the sharing, dissemination, and discovery of knowledge in photonics and electromagnetics, while facilitating collaborative synergies between mathematicians, physicists, and engineers. It encourages both curiosity-driven research in science and technology-inspired research in engineering. This knowledge contributes to advancing global standards and improving the quality of life worldwide. Additionally, TEMA is committed to mentoring and supporting junior researchers, scientists, and engineers, who will play a pivotal role in shaping the future of technologies related to electromagnetics.

The mission of TEMA is to establish a global forum and collaborative environment for researchers to exchange and discuss their findings in a harmonious, inclusive manner. TEMA sponsors PhotonIcs and Electromagnetics Research Symposium (PIERS), also known as Progress In Electromagnetics Research Symposium, and the PhotonIcs and Electromagnetics Research  Journals (PIER Journals). PIERS and PIER Journals aim to promote and accelerate the growth of science and technology worldwide, particularly in areas related to Maxwell’s equations. This encompasses a wide range of frequencies, length scales, and topics, from classical electromagnetics to quantum optics and electromagnetics. Given the breadth and depth of this field, priority will be given to emerging and innovative areas. PIERS will serve as a platform for networking, knowledge sharing, and dissemination, bringing together scientists and engineers from across the globe. Supported by the open-access PIER Journals, this platform will play a key role in advancing TEMA's mission.

In the year 1989, TEMA co-sponsored the 1st Progress in Electromagnetics Research Symposium (PIERS) held in Boston, Massachusetts, 25-26 July. The Symposium was followed by an NSF workshop on future directions in electromagnetics research, also co-sponsored by the Academy. Subsequent PIERS have been held in various cities around the world, including Cambridge, Pasadena, Noordwijk, Seattle, Innsbruck, Hong Kong, Nante, Taipei, Osaka, Singapore, Honolulu, Pisa, Nanjing, Hangzhou, Prague, Beijing, Rome, Toyama and etc. Since PIERS 2013 in Stockholm, PIERS has evolved from a mainly EM-based symposium to become the confluence of microwave and optics/photonic communities with over 1000 registered participants.
