      Wee, Fwen Hoon; Soh, Ping Jack; Mohd Suhaizal, Abu Hassan; Nornikman, Hassan; Mohd Ezanuddin, Abdul Aziz (Institute of Electrical and Electronics Engineering (IEEE), 2009-11-03)
      Principles to determine dielectric properties measurement using microwave free-space transmission measurements technique is presented in this paper. The project's main objective was to measure the dielectric properties of ...

    • Microwave wedge absorber design using rice husk - An evaluation on placement variation 

      Nornikman, Hassan; Soh, Ping Jack; Fareq, Malek, Dr.; Azremi, Abdullah Al Hadi; Wee, Fwen Hoon; R. Badlishah, Ahmad, Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
      Placement variation is one example of parameters that critically affects the performance of RF absorbers. In this work, four designed variation patterns - W, X, Y, and Z were discussed to compare the reflectivity (Sll) ...

    • Parametric studies of the pyramidal microwave absorber using rice husk 

      Nornikman, Hassan; Fareq, Malek, Dr.; Soh, Ping Jack; Azremi, Abdullah Al Hadi; Wee, Fwen Hoon; Hasnain, A. (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Agriculture waste has potential to be used as an alternative material for the microwave absorber used in the anechoic chamber. Compared to the current materials used, such as polystyrene and polyurethane, agricultural waste ...

    • Setup and results of pyramidal microwave absorbers using rice husks 

      Nornikman, Hassan; Fareq, Malek, Dr.; Ahmed, M.; Wee, Fwen Hoon; Soh, Ping Jack; Azremi, Abdullah Al Hadi, Dr.; Ghani, S. A.; Hasnain, A.; Taib, M. N. (EMW Publishing, 2011)
      Agricultural wastes are considered not useful and are commonly dumped or burned after crop harvesting. Rice husks from paddy (Oryza sativa) are example of agricultural wastes. Rice husks have been investigated as the ...
