Research Interests

Dr. Hany Taher earned his bachelor degree at 1993 from Benha university- Egypt, then obtained his Master degree from Cairo university- Egypt in 1999 and got his PhD degree from catholic university- Leuven- Belgium in 2006, all are in electronics and electrical communications engineering. He has about 25 years experience in the academic field at many institutes and universities. He is currently an assistant lecturer with the department of Aerospace, Mechanical and Electronics Engineering within the School of Engineering at Institute of Technology Carlow. The main research interests of Dr. Hany includes, but not limited to-

  • Design Rf and mW (millimetre waves) components, such as, Antennas, Filters, Power dividers, Negative group delay circuits, duplexers,…etc.
  • Design Rf circuits, such as, planer wireless power transfer units, interference cancellation circuits and mutual coupling reduction between antenna elements in MIMO systems.
  • Using artificial intelligent techniques such as ANN (Artificial Neural Network) LS-SVM (Least Square Support Vector Machine) ANFIS(Adaptive Network Based Fuzzy Interference System) to build Computer Aided Design (CAD) tools for RF/microwaves circuits.
  • Small signal and compact modelling of active devices, such as, HBT and LDMOSFET, as well as, behaioural modelling of analog circuits, such as, power amplifier and Lin driver.
  • Using method of lines as a numerical technique to analyze complex electromagnetic problems.
