Comprehensive investigation towards microwave elimination by using organic composite solid brick microwave absorber / Muhammad Irsyad Safwan Nasharuddin

Waste and radiation pollution has become a serious problem in this recent days. Uncontrollable waste disposal has affecting environmental issues while microwave radiation lead to various health issues. To dealing with this issue, organic composite brick absorber is design and fabricated. This study will show the capability of organic material used which is rice husk, coconut husk and sawdust as an absorbing material combined with cement as it based. CST Microwave Studio Suite software are used to obtained the simulation result of the designed absorber. Free space arch reflectivity measurement method is used to investigate the absorption performance of the design absorber at frequency range 8 to 12 GHz. This study also will include the absorption performance of the design absorber with the commercial flat absorber as it benchmarks. From this study, rice husk has the best absorption performance followed by sawdust and after that coconut husk.
