The latest trends in standards and standardization related to electromagnetic compatibility (EMC) were shared, and a forum was provided to examine related R&D technologies, thereby increasing the understanding of electromagnetic technology among industry professionals.

'EMC FEST 2021', hosted by the Ministry of Science and ICT and organized by the Electromagnetic Technology Research Institute of the Korea Electromagnetic Association, was held at the Hanla Hall in the Grand Ballroom of Seoul Dragon City on the 30th.

This event has been held annually since 2007 to promote the related industry by allowing those working in the electromagnetic wave industry to exchange information and promote domestic electromagnetic wave material/component products.

In the presentation that day, Dr. Choi Hyung-do of ETRI presented 'EM-X research for creating a safe radio environment' as the topic, and provided safety in response to the surge in national conflicts and civil complaints about electromagnetic waves in daily life with correct information, and △provided approval/inspection of ultra-high frequency devices such as 5G and autonomous driving, and a suitability assessment system, etc. He stated that we must take preemptive measures such as new radio wave management and countermeasures against abnormal radio wave interference to ensure safe and convenient use of electromagnetic waves where people and objects can coexist.

To this end, he mentioned that it is necessary to expand EM-X technology support, establish support infrastructure based on industry-academia-research business chains, foster integrated engineers responding to new technologies, and strengthen electromagnetic safety response at major infrastructure facilities.

Next, Professor Park Byeong-gwon of Daerim University shared information on the standardization trends of the TC 77 committee, a technical committee under the IEC established to determine the electromagnetic compatibility level so as not to degrade the performance of power equipment or electrical and electronic devices.

Regarding the ‘Draft of Revisions to Domestic EMC Standards and Testing Methods’, Lee Il-yong, a researcher at the National Radio Research Agency, shared information.

Regarding the expansion of the radiation immunity frequency range of low-voltage switchgear and control devices from 80 MHz–2 GHz to 80 MHz–2.7 GHz, the reason for the revision was explained as follows: As technological advancements have led to increasingly high-performance and multi-functional devices, the number of factors that can cause performance degradation and malfunctions due to external electromagnetic waves has increased.

Regarding the addition of the 3m radiation interference tolerance standard for the 30MHz∼1GHz band, it was reported that major foreign countries are applying it, and that the scope of choice for industries has been expanded so that they can choose between the existing 10m and the new 3m tolerance standard, taking into consideration the reduced cost burden on industries and testing institutions and the effect of easing prior regulations.

Regarding the revision of EMC test methods, the main revisions were explained for △KS C 9816-1-1 Measuring equipment △KS C 9816-1-2 Auxiliary equipment for conducting disturbance measurements △KS C 9816-1-2 Interference power △KS C 9610-6-4 Electromagnetic interference standards for devices used in industrial environments △KS C 9814-1 Part 1: Emission △KS C 9814-2 Part 2: Immunity, etc.

Next, Dong-Geun Choi, a researcher at the National Radio Research Agency, said,The 'Status of the Public Notice on Human Protection from Electromagnetic Waves and Major Revisions' was announced.

Regarding the 'Method for Testing High-Intensity Electromagnetic Fields for Aircraft', Senior Researcher Lee Gun-won of the Korea Testing Laboratory stated that the SAE ARP 5583 test method was established to address the following complex issues: △ensuring the safety of electronic aircraft systems; △reduced electromagnetic shielding capability due to the use of composite materials in aircraft design; △increased system sensitivity due to the increased use of data buses, integrated circuit electronic equipment, etc.; and △HIRF environment due to increased sequence and output frequency of RF transmitters.

Next, the test regulations were explained with a focus on Level A, which is defined as a system that has the highest priority on the lives of pilots and passengers, as a system that enables safe flight and landing.

In addition, the HIRF facility of KTL Aviation Electronics Technology Center was introduced.

Next, △ Lee Dong-gyun, CEO of Themis R&D, 'Design Tip of EMI/EMC for 5G' △ 4th Industrial △ Dr. Jeong Seong-il, 'Shielded Cables Modeling and Transfer Impedance Validation using Triaxial Setup' △ Lee Seong-hun, Manager of IceSpec, 'Analysis of the Impact of Common Mode Choke on CAN Communication' △ Dr. Kim Chang-gyun of Moasoft, 'Automation of Analysis Based on Virtual Digital Twin Using Artificial Intelligence' △ Dr. Koo Jong-min of Korea Institute of Science and Technology, '2D Materials for Electromagnetic Interference Shielding' △ Lee Moon-gyu, Professor of Seoul City University, 'ICT Megatrends and Future Radio Technology' △ Park Hyeon-ho, Professor of Suwon University ‘ The latest technology R&D research such as 'Electromagnetic shielding technology outlook for future automobiles' was shared.

An official from the Electromagnetic Engineering Research Institute said, “We will continue to share technical information related to electromagnetic waves and provide support so that it can be of practical help to those in the relevant industry.”
