Published a research team from the Faculty of Engineering at Kufa University consisting of: Associate Professor Dr. Abdul Kadhim Amin Hassan, Associate Professor Janan Hamid Saadi and Assistant Teacher Amin Mohammed Taqi scientific research entitled(Frequency scanning technique to measure the electromagnetic properties of electromagnetic material in a wide frequency band using wave guide sensor and numerical modeling In the International Journal of Microwave and Optical Technology, which is located within the scopus containers.Electromagnetic radiation absorbers in the microwave frequency range play a major role in industrial and military applications, they are used in the concealment of metal objects such as aircraft from radar systems, as well as in protection and immunization operations from the impact of radio waves from the detection of absorption. The total ity of radio waves and the absence of any reflection or permeability using these materials, where they are designed and manufactured from materials overlapping with your name and electromagnetic properties with specific and precise values for this purpose. For the purpose of measuring these values in a full, accurate and rapid manner on site as a result of their exposure to weather conditions or in the laboratory at the time of manufacturing, several methods have been developed for this purpose using mathematical analytical modeling to measure these quantities using certain hypotheses, resulting in a certain percentage of error in the clearing values. Using these methods. Most of these methods are applied at individual frequencies, where measurement must be made at each frequency at which these quantities are required and cannot be used in a wide frequency band. In this research, the frequency scanning technique was used to measure these quantities using numerical modeling, which has the ability to model the geometric shape mathematically efficiently, where the proposed method helps to measure these quantities at a wide frequency range in one step without having to re-measure at each frequency within The required frequency range. The results obtained for models of these materials showed that they matched those published by manufacturers of these materials compared to methods that use mathematical analytical modeling at individual frequencies.
