Green microwave radiation absorbing paint

This paper investigates the capability of oil palm ash paint as green-absorbing material in a way to absorb microwave radiations. The paint is coated on three different wall materials which are elephant board, plywood and cement. The absorb performance of the paint is observed using the simulation result of Computer Simulation Technology (CST) Microwave Studio software. Meanwhile, the exact performance of the absorber is carried out via the measurement of absorption performance which shows a minimum average of absorption is -4.9 dB for all materials.
