The intelligent reflecting surfaces (IRS) can be implemented in radio systems in order to provide the cooperative communication services. In fact, the cooperative communication can increase the received signal strength at the communication receiver. Moreover, it can let transmitters send their signals with low power. The electromagnetic interference (EMI) can degrade the communication system performance. The total interfering power, affecting a communication system, can increase the bit error rate (BER). The large BER value is not good issue as it leads to a low system performance. Therefore, there should be tools and techniques in order to balance and compensate the existing BER. In fact, there are a lot of tools that can compensate the BER effect. We are concerned with the cooperative millimeter wave systems that are based on IRSs which are affected by EMI. Such systems have non-satisfied performance due to the high path losses as well as the existing EMI. These systems will be modeled and simulated. Furthermore, the space time block codes (STBC) are applied in order to compensate the bad performance of such systems. Really, the STBC codes can greatly compensate the bad effects of the high path loss as well as the large interference.

This paper presents the modelling and simulation of a protection system for equipment in the oil and gas industry with various RF grids and enclosures against 500 MHz electromagnetic interference (EMI). COMSOL Multiphysics®Modelling software was used in this study. Electric and magnetic fields distributions were determined by using the Generalized Minimal Residual Method (GMRES) which was integrated into COMSOL Multiphysics® Modelling software. Simulation results indicated that larger RF grid size contributed to the higher electric and magnetic field on equipment. Furthermore, without RF grid, electric and magnetic fields on the equipment were increased significantly (up to 100x). The maximum electric and magnetic fields were found to be near resonance enclosure size (299 mm for 500 MHz frequency source). The results showed that the presence of the RF grid for the EMI protection system was essential.
