A Concept of LNA with Low Input Impedance Using Common Base BJT for Low-Field MRI
Aleksei A. Nasonov, Mikhail V. Murzin, Nikolay V. Anisimov +4
Purpose: In magnetic resonance imaging (MRI), preamplifier decoupling is used to improve the signal-to-noise ratio of a multichannel receive coil array. In low-field and ultra-low-…
Double-resonant decoupling method in very dense dipole arrays
Masoud S. M. Mollaei, Anna Hurshkainen, Sergei Kurdjumov +1
In this paper an approach for broadening of operational band in a dense array of dipole antennas by implementing passive split-loop resonators (SLRs) as decouplers is presented. Co…
Experimental observation of hybrid TE-TM polarized surface waves supported by hyperbolic metasurface
Oleh Y. Yermakov, Anna A. Hurshkainen, Dmitry A. Dobrykh +5
Hyperbolic metasurfaces have gained significant attention due to their extraordinary electromagnetic properties to control propagating plane waves, but the excitation and propagati…
Decoupling of Two Closely Located Dipole Antennas by a Split-Loop Resonator
Masoud Sharifian Mazraeh Mollaei, Anna Hurshkainen, Sergey Kurdjumov +2
In this letter, we theoretically and experimentally prove the possibility of the complete passive decoupling for two parallel resonant dipoles by a split-loop resonator. Unlike pre…
Passive Decoupling of Two Closely Located Dipole Antennas
Masoud Sharifian Mazraeh Mollaei, Anna Hurshkainen, Sergei Kurdjumov +2
In this paper, we prove that two parallel dipole antennas can be decoupled by a similar but passive dipole located in the middle between them. The decoupling is proved for whatever…
