iWEM started in Taipei in 2010 and was named as “International Conference on Applications of Electromagnetism and Student Innovation Awards” (2010 ICAE/SIA). The conference was renamed in 2011 as “IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition” (2011 IEEE iWEM). It provides not only an international platform for scientists and engineers to exchange their ideas, but also a good venue for young scholars and research students to demonstrate their innovative works and results. We sincerely invite all experts and scholars to participate and welcome contributions to Workshop Proceedings. Meanwhile, we sincerely expect everyone can enjoy the beautiful Penghu island in Taiwan.
