Investigation of metamaterial coated conducting cylinders for achieving transparency and maximizing radar cross section
Ircı, Erdinç; Ertürk, Vakur B. (IEEE, 2007)Recently, reducing the radar cross sections (RCS) of various structures to achieve transparency and obtaining resonant structures aimed at increasing the electromagnetic intensities, stored or radiated power levels have ... -
Investigation of planar and conformal printed arrays for MIMO performance analysis
Tunç, Celal Alp; Ircı, Erdinç; Bakır, Onur; Aktaş, Defne; Ertürk, Vakur B.; Altıntaş, Ayhan (IEEE, 2006)MIMO channel capacity of printed arrays with dipole elements is analyzed. A MIMO channel model based on electric fields is used. The effects of mutual interactions among the array elements through space and surface waves ... -
A model with electric fields for the inclusion of mutual coupling effects in the MIMO channel
Tunç, Celal Alp; Ircı, Erdinç; Bakır, Onur; Aktaş, Defne; Ertürk, Vakur B.; Altıntaş, Ayhan (IEEE, 2007)Multiple input multiple output (MIMO) wireless communication systems have been a focus of interest, due to their ability to increase the capacity in rich scattering environments by using multi-element antenna arrays both ... -
Wave propagation in metamaterial structures and retrieval of homogenization parameters
Ircı, Erdinç (Bilkent University, 2007)Electromagnetic wave propagation in metamaterial structures (metamaterial slabs, metamaterial cylinders, metamaterial coated conducting cylinders etc.) are investigated. Scattered and transmitted electromagnetic fields ...
