Congratulations to Mahdi Assefzadeh, a Ph.D. student in electrical and computer engineering (ECE) for receiving an IEEE MTT-S Graduate Fellowship for 2017! Assefzadeh, a member of ECE assistant professor Aydin Babakhaniâ€™s Rice Integrated Systems and Circuits (RISC) laboratory, was recognized for his work in Terahertz technology.
â€śThis is very exciting for me because it is a prestigious fellowship for Ph.D. students, and very competitive,â€ť Assefzadeh said.
2017 is the third year in a row a student from the RISC lab has received an MTT-S fellowship. In 2016, Himanshu Aggrawal received the award, also for his work in Terahertz, and in 2015, Xuebei Yang received the honor for his work in medical technology.
In his application, Assefzadeh proposed a novel THz pulse generation technique, Direct Digital-to-Impulse (D2I), that is capable of radiating high-power picosecond pulses.
Assefzadeh is working on a digitally programmable THz pulse-radiating array in silicon. The array will form narrow beams of broadband THz pulse radiation, which can be used in a high-resolution, long-range active spectral imaging system. The array will enable a 300Gbps wireless link over a 300m distance, to serve as the next-generation transmitter for long-range Terabit per second wireless communication.
â€śThis will be the first broadband, high-power and highly directive beam-steerable THz source with a repetition rate of 100GHz and integrated digital programmability,â€ť Assefzadeh noted.
Assefzadeh will travel to Honolulu in June to be recognized for the achievement, which includes a certificate of recognition, the $6,000 fellowship, and travel reimbursement to the conference.
