Ravi Tandon, assistant professor of electrical and computer engineering, was recently appointed an editor for the publication IEEE Transactions on Wireless Communications.

Tandon’s research focuses on several fields, including wireless communications, signal processing, and wireless security and privacy. His achievements have been recognized by the Institute of Electrical and Electronics Engineers before when he won the Best Paper award at GLOBECOM 2011.

IEEE Transactions on Wireless Communications, or TWC, aims to publish high-quality, peer-reviewed, original papers that advance the theory and applications of wireless communication systems and networks.

Springer recently published “Advanced Optical and Wireless Communications Systems” by Ivan B. Djordjevic, professor in the UA Department of Electrical and Computer Engineering

The book introduces readers to advanced topics in:

  • wireless communications
  • free-space optical communications
  • indoor optical wireless (infrared) communications
  • fiber-optics communications

Although these communication systems have been considered separate disciplines, they share fundamental concepts, and the book rests on the idea that these systems should be viewed in a unified fashion. Djordjevic’s book provides straightforward guidance on communication fundamentals that can be readily applied to research and practical applications.



Hao XinDepartment of Electrical and Computer Engineering professor Hao Xin was elevated to IEEE fellow "for his contributions to electromagnetic metamaterials and 3-D printing of metamaterial structures" in January 2018.

Metamaterials are designed to have properties not found in nature, like a negative refractive index, which bends energy waves backward. Xin’s research into negative refraction has brought the world one step closer toward the possibility of invisibility cloaks. He has also developed ways of 3-D printing antennas and radio frequency, or RF, circuits, which are used to wirelessly transfer information.

Kwai-Man Luk, the chair professor of electronic engineering at City University of Hong Kong, nominated Xin for the award. He wrote in his nomination that metamaterials are often difficult and expensive to construct, but that Xin has discovered ways to successfully 3-D print them.

"His research outcome has not only enabled efficient fabrication of electromagnetic metamaterials, but also led to new designs that were not able to be fabricated before," he wrote.

Electrical and computer engineering associate professor Wolfgang Fink has been named fellow for the Arizona Center for Accelerated Biomedical Innovation for his research and advancements in the field of biomedical technologies.

"I felt very honored to receive this award," said Fink, who holds a joint faculty position in biomedical engineering. "It was definitely very nice to receive this recognition."

ACABI's purpose is to bring together biomedical experts to collaborate for the goal of accelerating the development of biomedical technologies.

"ACABI is like a think tank," Fink said. "So when a medical problem that involves engineering presents itself, the purpose is to brainstorm and come up with ways to solve it."

Fink's colleague, UA cardiologist and ACABI leader Marvin Slepian, calls ACABI "a creative engine," and Fink is an important cog in that engine. He is a leader in research and development for artificial retinas and vision science for the center, with 18 issued patents and several more pending. His goal is to "give vision back to blind people."
