    • Determination of moisture content in oil palm fruits using a five-port reflectometer 

      Yee, Lee Kim; Zulkifly, Abbas; Mohamad Ashry, Jusoh; You, Kok Yeow; Cheng, Ee Meng (MDPI Publishing, 2011-04-06)
      This paper presents the development of a PC-based microwave five-port reflectometer for the determination of moisture content in oil palm fruits. The reflectometer was designed to measure both the magnitude and phase of ...
    • Precise moisture monitoring for various soil types using handheld microwave-sensor meter 

      You, Kok Yeow; Lee, Chia Yew; Then, Yi Lung; Chong, Sheau Huey Chen; You, Li Ling; Zulkifly, Abbas; Ee Meng, Cheng, Dr. (IEEE Conference Publications, 2013)
      A handheld microwave reflectometer-sensor system is developed to operate from 1.35 to 1.95 GHz and used to measure volumetric and gravimetric moisture content in various types of soils from 0% to 45%. A small monopole ...
    • Study of dual open ended coaxial sensor system for calculation of phase using two magnitudes 

      Kim, Yee Lee; Boon, Kuan Chung; Kok Yeow, You; Ee Meng, Cheng, Dr.; Zulkifly, Abbas (Institute of Electrical and Electronics Engineers (IEEE), 2014-01)
      A dual open ended coaxial sensor system to determine complex permittivity was studied in detail. This paper focuses on determination of a reflection coefficient phase from two magnitudes using modified capacitance model ...
