    • 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 ...
    • Effect on source signal condition for pyramidal microwave absorber performance 

      Nornikman, Hassan; Fareq, Malek, Dr.; Soh, Ping Jack (Institute of Electrical and Electronics Engineers (IEEE), 2010-05-11)
      In designing a microwave absorber for anechoic chamber, there are many condition can affect the performance of microwave absorber. In this work, four conditions are discussed to compare the reflectivity or S11 of the ...
    • Free space measurement technique on dielectric properties of agricultural residues at microwave frequencies 

      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) ...
    • Performance simulation of pyramidal and wedge microwave absorbers 

      Nornikman, Hassan; Soh, Ping Jack; Azremi, Abdullah Al Hadi; Anuar, Mat Safar (Institute of Electrical and Electronics Engineering (IEEE), 2009-05-25)
      Anechoic chambers signal absorption capability is directly correlated to its performance. One of the main components in enabling signal absorption is the design and material used in designing the absorbers. Two of the main ...
    • Reflection loss performance of hexagonal base pyramid microwave absorber using different agricultural waste material 

      Nornikman, Hassan; Fareq, Malek, Dr.; Soh, Ping Jack; Azremi, Abdullah Al Hadi (Institute of Electrical and Electronics Engineers (IEEE), 2010-11-08)
      Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal ...
