Ultraslow long-living plasmons with electromagnetically induced transparency
David Ziemkiewicz, Karolina Słowik, Sylwia Zielińska-Raczyńska
We analytically examine propagation of surface plasmon polaritons (SPPs) at a thin metallic film between glass substrate and electromagnetically-induced-transparency (EIT) medium.…
Tunable narrow-band plasmonic resonances in electromagnetically-induced-transparency media
David Ziemkiewicz, Karolina Słowik, Sylwia Zielińska - Raczyńska
The spectral response of a plasmonic nanostructure may heavily depend on the refractive index of its surroundings. The key idea of this paper is to control this response by coheren…
Controlled processing of signal stored in metamaterial with tripod structure
S. Zielińska-Raczyńska, D. Ziemkiewicz
In the present paper we have discussed in detail electromagnetically induced transparency and signal storing in the case of one signal pulses propagating in a classical electric me…
Frequency shifts of radiating particle moving in EIT metamaterial
S. Zielińska-Raczyńska, D. Ziemkiewicz
Nowadays, there is considerable interest in metamaterials which realize the electromagnetically induced transparency in a classical system. We consider the frequency shifts of part…
Complex Doppler effect in left-handed metamaterials
David Ziemkiewicz, Sylwia Zielińska-Raczyńska
The Doppler shift is investigated in one-dimensional system with moving source. Theoretical findings are confirmed in numerical simulations of optical and acoustical waves propagat…
