    • Development of pyramidal microwave absorber using sugar cane bagasse (SCB) 

      Liyana, Zahid; Mohd Fareq, Abd Malek, Dr.; Nornikman, Hassan; Nur Adyani, Hj. Mohd Affendi; Azuwa, Ali; Nuriziani, Hussin; Badrul Hisham, Ahmad, Dr.; Mohamad Zoinol Abidin, Abd. Aziz (EMW Publishing, 2013)
      The need to find ways to effectively utilize the large quantities of agricultural waste that are produced is indicative of the huge potential associated with producing an alternative pyramidal microwave absorber for anechoic ...

    • 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 ...

    • A simple technique for improving the anechoic performance of a pyramidal absorber 

      M. Nadeem, Iqbal; Mohd Fareq, Abd. Malek, Dr.; Yeng, S. Lee; Liyana, Zahid; Muhammad Iqbal, Muhammad Hussain, Dr.; Mohd F. H., A Malek; Nur Fairuz, Mohamed Yusof; Norshafinash, Saudin; Noor Anida, Abu Talib (EMW Publishing, 2013)
      In this paper, we propose a very simple technique that offers an extra degree of freedom to optimize the design of a tire dust-based absorber with reduced height. Cladding is a technique that is used to enhance the surface ...

    • Study and simulation of an edge couple split ring resonator (EC-SRR) on truncated pyramidal microwave absorber 

      Nornikman, Hassan; Badrul Hisham, Ahmad, Assoc. Prof. Dr.; Mohamad Zoinol Abidin, Abd. Aziz; Mohd. Fareq, Abd. Malek, Dr.; H, Imran; Ali Rani, Othman (EMW Publishing, 2012)
      Split ring resonator (SRR) structure can potentially be incorporated onto the truncated pyramidal microwave absorber. This study considers three different patterns of edge couple split ring resonator (EC-SRR) designs. Each ...

    • The use of dielectric mixture equations to analyze the dielectric properties of a mixture of rubber tire dust and rice husks in a microwave absorber 

      Cheng, Ee Meng; Mohd Fareq, Abd Malek, Dr.; Manjur Murshed Zahid, Ahmed; You, Kok Yeow; Lee, K. Y.; Nornikman, H. (Progress in Electromagnetics Research (PIER), 2012)
      A change in the relative proportions of a mixture of rubber tire dust and rice husks will cause a change in the mixture's electrical permittivity and its ability to absorb electromagnetic energy. An openended coaxial probe ...
