The study of innovative anti-microwave brick walls by using POFA as partial cement replacement

We live in a generation that relies upon technologies. As a result of the rapid growth of wireless devices and networks, humans are exposed to radiation. The increases of this unwanted radiation surround raise concerns about the possible human health effect and the impact on electronic devices. This...

We live in a generation that relies upon technologies. As a result of the rapid growth of wireless devices and networks, humans are exposed to radiation. The increases of this unwanted radiation surround raise concerns about the possible human health effect and the impact on electronic devices. This project aims to develop anti-microwave brick walls with the composition mixture of absorbing materials and investigate the absorption performance of anti-microwave bricks in the operating frequency range of 1 GHz to 12 GHz. In this project, anti-microwave brick walls were developed by using a mixture of agricultural waste, which is palm oil fuel ash (POFA). The absorption performance of the anti-microwave brick walls was measured by using Naval Research Laboratory (NRL) Arch free space method. The study showed that anti-microwave brick walls contain a high percentage of POFA have the best absorption performance compared to brick walls contain a low percentage of POFA. Anti-microwave brick wall contains 40% POFA produced the best absorption performance with maximum absorption of 18.25 dB in X-band frequency (8-12 GHz). This can be concluded that the higher the amount of POFA, the better the absorption performance of the anti-microwave brick walls. Copyright 2021 Elsevier Ltd. All rights reserved.
