Personal profile


Lei Wang received the Ph.D. degree in electromagnetic field and microwave technology from Southeast University, Nanjing, China in March 2015.

From September 2014 to September 2016, he was a Research Fellow and Postdoc in the Laboratory of Electromagnetics and Antennas, Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland.

From October 2016 to November 2017, he was a Postdoc Research Fellow in Electromagnetic Engineering Laboratory of KTH Royal Institute of Technology in Stockholm, Sweden.

From November 2017 to February 2020, he was an Alexander von Humboldt Fellow in the Institute of Electromagnetic Theory of Hamburg University of Technology (TUHH) in Hamburg, Germany. 

From March 2020 to present, he is an assistant professor in the Institute of Sensors, Signals & Systems of Heriot-Watt University in Edinburgh, UK.

He was awarded the Chinese National Scholarship for PhD Candidates in 2014 and was granted the Swiss Government Excellence Scholarship to conduct research on SIW horn antennas and applications in 2014. He was also granted by the Alexander von Humboldt Research Foundation to take research on antenna modelling and optimization in 2016. Moreover, he received the Best Poster Award in 2018 IEEE International Workshop on Antenna Technology (iWAT).

Research interests

His research includes the antenna theory and applications, active electronically scanning arrays (AESAs), integrated antennas and arrays, substrate-integrated waveguide antennas, leaky-wave antennas and wireless propagation.

1. Substrate-integrated Edge Antennas

Electromagnetic (EM) radiation from substrate edges at high frequencies can be intentionally used for antennas. With the SIW technology, horn antennas are possible to be integrated in the substrate. However, there is mismatching between the substrate edges and free space. We introduce several impedance matching techniques to enable the EM waves smoothly radiating in wide bands. Furthermore, we present several integrated lens techniques to improve the aperture efficiency.

2. Leaky-wave Antennas

Leaky-wave antennas (LWAs) offer interesting features for mmW wireless applications, since they offer high directivity, low losses and wide impedance bandwidth. Due to the dispersive nature, the directive beam is scanned with frequencies. However, the frequency-dependent beam steering is a drawback for highly directive point-to-point broadband mmW wireless links, as the pattern bandwidth is narrow. To overcome it, we proposed prism lens loaded LWAs for wideband fixed-direction communication.

3. EM Waves Carrying Orbital Angular Momentum

Radio waves carrying orbital angular momentum (OAM) offer interesting twisting wave front and orthogonal OAM modes. While many studies focus on the generation of OAM waves, there are many fundamental understandings of the OAM based communication are missing. We proposed mixed-mode scattering matrices to investigate the communication, reflection and interference of the OAM based communication links in the free space or in certain environments. 

4. mmW Active Electronically Scanned Arrays

Phased arrays with active components integrated in array elements and sub-arrays are investigated for mmW future communication application, aiming for high power efficiency and singal linearity.
