Design of Ultrawide Bandwidth Electromagnetic Wave Absorbers with Square Patch Frequency Selective Surfaces with Different Geometries
Tian Liu, Sung-Soo Kim
Korean J. Met. Mater. 2020;58(5):326-333.   Published online 2020 Apr 20
DOI: https://doi.org/10.3365/KJMM.2020.58.5.326

A reliable and efficient numerical method is presented for the design of broadband absorbers, fabricated by layering two square patch-frequency selective surfaces (SP-FSS) with different geometries on a grounded dielectric substrate. The circuit parameters of the inductance and capacitance of the SP-FSS were retrieved using the strip wire conductor model...... More

Design and Fabrication of Metamaterial Absorbers Used for RF-ID
RF-ID용 메타소재 흡수체의 설계 및 제조
Yo-Han Ryu, Sung-Soo Kim
류요한, 김성수
Korean J. Met. Mater. 2020;58(2):131-136.   Published online 2020 Jan 8
DOI: https://doi.org/10.3365/KJMM.2020.58.2.131

Radio frequency identification (RF-ID) uses electromagnetic fields to automatically identify and track tags attached to objects. In response to the need to suppress the electromagnetic interference between adjacent RF-ID equipment or systems, this study aims to achieve a thin and multi-resonance absorber using metamaterials composed of patterned grids on a.....

Han-Shin Cho, Sung-Soo Kim
조한신, 김성수
Korean J. Met. Mater. 2019;57(11):741-746.   Published online 2019 Nov 5
DOI: https://doi.org/10.3365/KJMM.2019.57.11.741

With the increased use of diverse electronics in the high frequency spectrum, high-performance absorbing and shielding materials are needed to ensure electromagnetic compatibility. Microwave absorbance of polymer composites of carbonyl iron powders with frequency selective surface (FSS) is investigated, focusing on the frequency of 5.8 GHz. Composite sheets were prepared.....

Electromagnetic Noise Absorption by Conductive Grid Films Prepared by Screen Printing Process
스크린 인쇄공정으로 제조한 그리드 전도막의 전자기 노이즈 흡수특성
Min-Sung Kim, Sung-Soo Kim
김민성, 김성수
Korean J. Met. Mater. 2017;55(8):576-580.   Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.576

To realize focused design near-field conduction noise absorbers for sub-GHz frequencies, this study proposes screen-printed conductive grid films. The films’ advantages include large-scale production and easy control of electrical properties. A conductive grid film with a resistance value of approximately 70 Ω was screen printed on polyimide film substrate and..... More

Calculation of Inductance, Capacitance, and Microwave Absorbance of Modified Square Loop Frequency Selective Surface
변형된 사각 루프 주파수 선택 표면의 인덕턴스, 커패시턴스 계산 및 전파흡수특성
Tian Liu, Sung-Soo Kim
류전, 김성수
Korean J. Met. Mater. 2017;55(6):412-418.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.412

The square loop (SL) is the typical pattern of a frequency selective surface (FSS) with high inductance (L) and capacitance (C). In this study, modified patterns including split square loop FSS (SSL-FSS) and I-type FSS (I-FSS) are proposed, and their L and C values were estimated using the equivalent circuit..... More
