Detection and quantification of alkali-silica-reaction (ASR) gel in cement-based mortars using microwave spectral and temporal transmission properties
Hasar, Uğur Cem; Öztürk, Hamdullah; Korkmaz, Hüseyin; Taşdemir, Ahmet; Bute, Musa; Niş, Anıl; Karaaslan, Muharrem; Çevik, Abdülkadir; Özkaya, Mehmet Akif (Elsevier, 2023)Microwave transmission measurements in time-domain, as a new measurement tool, were carried out to detect and quantify alkali-silica-reaction (ASR) within mortar specimens. To examine the potential of time-domain transmission ... -
Improved line–line method for propagation constant measurement of reflection-asymmetric networks
Hasar, Uğur Cem; Öztürk, Hamdullah; Korkmaz, Hüseyin; İzgınlı, Mücahit; Karaaslan, Muharrem (Elsevier, 2022)A new formalism using line-line measurements is proposed to improve the accuracy of propagation constant measurement of reflection-asymmetric networks using non-calibrated scattering (S-) parameters. For this measurement, ... -
Radiation pattern reconfigurable cubical antenna array for 2.45 GHz wireless communication applications
Alkurt, Fatih Özkan; Ünal, Emin; Palandöken, Merih; Abdulkarim, Yadgar I.; Hasar, Uğur Cem; Karaaslan, Muharrem (Springer, 2022)In this paper a single-fed four-faced multidirectional compact antenna is introduced for 2.45 GHz indoor wireless applications. Firstly, a slotted patch antenna is designed to operate at 2.45 GHz and its equivalent circuit ... -
A study on electronically controllable beamforming monopole antenna for telecommunication applications
Alkurt, Fatih Özkan; Ünal, Emin; Palandöken, Merih; Altıntarla, Gizem; Abdulkarim, Yadgar I.; Hasar, Uğur Cem; Karaaslan, Muharrem (Taylor and Francis, 2022)The design, analysis, and prototyping of an electronically controllable beamforming monopole antenna (ECBMA), which could be a good candidate for ceil-mounted wireless telecommunication systems, are reported. The proposed ...
