Activated carbon is produced by microwave heating method. We designed microwave applicator for processing biomass waste into activated carbon. To obtain the optimal design, CST Microwave studio was selected to simulate microwave radiation inside the applicator. In this work, simulation process has been done to find out microwave radiation with the change a waveguide port position and microwave cavity shape. In the measurement of microwave radiation, we used electrical field (E-field) monitor at frequency 2.45GHz. The result shows that applicator with hexagonal shape has the best performance in power accepted and power outgoing, most uniform E-field radiation in the sample. Microwave applicator for heating process biomass waste into activated carbon can be optimized with adding some stirrer mode. © Published under licence by IOP Publishing Ltd.
