He was a member of the editorial board ofthe PERTANIKA journal for more than 9 years (1997 – 2006). He truly enjoys servingthe society as a scientist and would continue to do so in future.

Current research:

Photoacoustic TechniqueThe photoacoustic effect is based on the generation of acoustic waves as theconsequence of modulated light absorption. The absorption of the incident energybeam and the subsequent non-radiative de-excitation relaxation processes give riseto a heat source in the sample. In the photoacoustic technique, the sample isenclosed in an airtight cell where the temperature oscillations from the illuminatedsurface of the sample will be communicated to the gas in the cell. The effect can besensed by a sensitive microphone that forms part of the inner cell wall. Physically theheating of the sample depends on the optical absorption and the heat diffuses fromthe sample to the surface. These two factors lead versatility to the technique forstudying optical absorption as well as thermal diffusivity of samples. The ultimate goalis to use this technique in determining glucose content in blood by in-situmeasurements.

Surface Plasmons Resonance TechniqueA surface plasmon (SP) is a collective excitation of the electrons at the interfacebetween a conductor and an insulator. Surface plasmons on a plane surface are non-radiative electromagnetic modes, that is, SPs cannot be generated directly by lightnor can they decay spontaneously into photons. The origin of the non-radiative natureof SPs is that the interaction between light and SPs cannot simultaneously satisfyenergy and momentum conservation. This restriction can be overcome by increasingthe effective wave vector (and hence momentum) of the light using a prism couplingtechnique. His interest at present is more in the applications of Surface PlasmonResonance particularly in multiple thin film systems. The presence of even very thinfilm gives measurable shifting of the resonance angle and broadening the reflectivitydip. These effects can be utilized to develop devices such as optical modulators andchemical sensors. To further enhance the lab’s capabilities for analyzing thin films, heis equipping his ATR reflectivity system with the ability to make ellipsometricmeasurements for variable angle and variable wavelength measurements.
