A Great Research Achievements of Bangladesh University

Dr. Md. Muhibbullah, Assistant Professor of EEE department of Bangladesh University (BU), has modified the electromagnetic wave energy equation in January 2017. (An Application of the Frequency Dependent Energy Equation of the Electromagnetic Wave the Explanation of the photoelectric effect)  It is a great achievement in the field of Applied Physics because the theory may create a revolution on the nature of light. He has done the research in collaboration with Prof Yasuro Ikuma, Kanagawa Institute of Technology (Japan) and Dr. M. Abdel Haleem, Fayoum University (Egypt). From the last few decades, the science community has been believing that light has two natures that are wave and photon. Dr. Muhibbullah experimentally demonstrated that the light is an electromagnetic wave only and it is not required to consider photon to explain photonic nature of light.

In 1905, Albert Einstein had explained the photoelectric effect based on quantum theory. However, only two phenomena of the photoelectric effect have been matched whereas some phenomena behaved opposite with the explanation of Albert Einstein. In December 2017, Dr. Muhibbullah has explained photoelectric effect based on their electromagnetic wave theory with Prof Ikuma. All (six) phenomena of the photoelectric effect have been matched with the explanation. Materials Research Society of Japan has accepted the explanation as oral presentation in their international conference in December 2017. Dr. Muhibbullah has been doing research on the interactions between the electron and the light based on electromagnetic wave theory.

Dr. Muhibbullah has also derived some more equations on semiconductor such as; “an equation of the width of the depletion layer for a step heterojunction”, “an equation of average lifetime of minority carriers in a semiconductor” and “estimation of the open circuit voltage of a pn junction from the results of the photo electrochemical measurement”. All theories have been published in high quality international journals.
