Multi-band polarization independent cylindrical metamaterial absorber and sensor application
Dinçer, Furkan; Karaaslan, Muharrem; Çolak, Şule; Tetik, Erkan; Akgöl, Oğuzhan; Altıntaş, Olcay; Sabah, Cumali (World Scientific Publishing Co. Pte Ltd, 2016)A multi-band perfect metamaterial absorber (MA) based on a cylindrical waveguide with polarization independency is numerically presented and investigated in detail. The proposed absorber has a very simple configuration, ... -
Optimizing the Gain and Directivity of a Microstrip Antenna with Metamaterial Structures by Using Artificial Neural Network Approach
Sağık, Metin; Altıntaş, Olcay; Ünal, Emin; Özdemir, Ersin; Demirci, Mustafa; Çolak, Şule; Karaaslan, Muharrem (Springer, 2021)The purpose of this study is to improve the gain and directivity of the microstrip patch antenna by means of metamaterial (MTM) structures. As it is known, antennas have power densities in a certain direction, and the ... -
