Multiwall Carbon Nanotube Time Delay Section

In this work, a multiwall carbon nanotube time delay section (MWCNTDS) is presented. For this purpose transmission line model (TLM) of a multiwall carbon nanotube (MWCNT) is used. The results of the analysis of a MWCNTDS are examined and discussed in detail. The results show that while the distance from the ground plane of the outer shell increases, time delay of a MWCNTDS increases. Time delay decreases while the value of inner radius or the total number of shells increases. Since the diameter increases with the increasing values of inner radius and the total number of shells, time delay decreases with increasing diameter. While time delay increases with increasing length of MWCNTDS, it decreases with increasing frequency.
