Linear to left- and right-hand circular polarization conversion by using a metasurface structure

Akgöl, Oğuzhan; Altıntaş, Olcay; Ünal, Emin; Karaaslan, Muharrem; Karadağ, Faruk (Cambridge University Press, 2018)

By using a metasurface (MS) structure, a linearly polarized wave is converted to circularly polarized waves. Both right- and left-handed circular polarizations (RHCPs and LHCP) are obtained by a simple configuration in the ...

Wideband metamaterial absorber based on CRRs with lumped elements for microwave energy harvesting

Bağmancı, Mehmet; Karaaslan, Muharrem; Altıntaş, Olcay; Karadağ, Faruk; Tetik, Erkan; Bakır, Mehmet (Taylor & Francis, 2018)

A novel metamaterial absorber structure is designed and characterized for microwave energy harvesting. The suggested structure is composed of two circular ring resonators with different dimensions. Due to harvesting ...
