Time-domain simulation of carbon nanotube dipoles at low-terahertz band

This communication presents a procedure for the analysis of carbon nanotube (CN) antennas directly in the time domain. The time-domain electric-field integral equation (TD-EFIE) for thin-wires, including external loads, is the procedure in which is based. Appropriate loads are calculated to match the physical response of single-walled carbon nanotube (CN) media to external electromagnetics fields. The time-domain formulation provides physical insight into characteristic effects of CN dipoles, such as slow-wave propagation and the existence of low-frequency resonances.
