    • Design of pyramidal microwave absorber using agriculture waste with different resin content percentage 

      Nornikman, Hassan; Soh, Ping Jack; Azremi, Abdullah Al Hadi; Wee, Fwen Hoon (Universiti Malaysia Pahang (UMP), 2009-06-20)
      Agriculture waste has many potential to produce an alternative and beneficial product for any suitable application such as microwave absorber for anechoic chamber. In this work, agriculture waste like rice husk from ...
    • 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 ...
    • Rubber tire dust-rice husk pyramidal microwave absorber 

      Mohd Fareq, Abd. Malek, Dr.; Cheng, Ee Meng, Dr.; O., Nadiah; Nornikman, Hassan; M., Ahmed; M. Z. A., Abd Aziz; A. R., Osman; Soh, Ping Jack; Azremi, Abdullah Al Hadi; A., Hasnain; Mohd Nasir, Taib (EMW Publishing, 2011)
      Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
    • 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 ...
