Comparative study between measurement and predictions using geometrical optics and uniform theory of diffraction for case of non-line-of-sight (NLOS) in indoor environment
Cheng, Ee Meng, Dr.; Zulkifly, Abbas, Prof. Madya Dr.; Mohd Fareq, Abd. Malek, Dr.; Lee, Kim Yee, Dr.; Kok, Yeow You; Khor, Shing Fhan, Dr. (Springer Science+Business Media New York, 2013-08)This paper describes the investigation and comparison of the accuracy of a deterministic model for a WLAN system in the indoor environment. The measurement system consisted of a spectrum analyzer and a log-periodic antenna. ... -
Experimental determination of the performance of rice husk-carbon nanotube composites for absorbing microwave signals in the frequency range of 12.4-18 GHz
Lee, Yeng Seng; Mohd Fareq, Abd. Malek, Dr.; Cheng, Ee Meng, Dr.; Liu, Wei Wen, Dr.; Kok, Yeow You; Muhammad Nadeem, Iqbal; Wee, Fwen Hoon, Dr.; Khor, Shing Fhan, Dr.; Liyana, Zahid; Mohd Fariz, Haji Abd Malek (EMW Publishing, 2013)Composites of rice husks and carbon nanotubes (RHC-NTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant ... -
