ELECTROMAGNETIC COMPATIBILITY DESIGN FOR KOMPSAT-2 [PDF]

Journal of Astronomy and Space Sciences, 2003
It is quite essential that requirements allocation and analysis would be done for the electromagnetic compatibility (EMC) of all units when designing a satellite. Although KOMPSAT-2 inherits relatively large portions of the electrical designs from KOMPSAT-1, it has a new instrument and different combinations of sensors and actuators as well as their ...

Ultra-Wideband Filtering 180° Hybrid Coupler With Super Wide Upper Stopband Using Swap Phase Inverter and Electromagnetic Bandgap Structures on Double-Sided Parallel-Strip Line

IEEE Access, 2018
In this paper, a multifunctional 180° hybrid coupler is proposed, with an ultra-wideband filtering response and a super wide upper stopband. The component, realized with double-sided parallel-strip line (DSPSL), is built up on the basis of a ...

Design, concepts, and applications of electromagnetic metasurfaces [PDF]

Nanophotonics, 2018
Abstract The paper overviews our recent work on the synthesis of metasurfaces and related concepts and applications. The synthesis is based on generalized sheet transition conditions (GSTCs) with a bianisotropic surface susceptibility tensor model of the metasurface structure. We first place metasurfaces in a proper historical context
