ABSTRACT: In this letter, a novel procedure is introduced for the simulation of carbon nanotube (CN) antennas directly in the time domain. This formulation is based on the time-domain electric- field integral equation (TD-EFIE) for thin-wires, including external loads. Appropriate loads have been derived to match the physical response of single-walled CN media to external electromagnetic fields. The results show good agreement with a validated frequency-domain formulation. The time-domain formulation provides physical insight into the well-known characteristic effects of CN dipoles, such as slow-wave propagation and the existence of low-frequency resonances.

ABSTRACT: This paper presents a numerically efficient approach for simulating nanowires at infrared and long optical wavelengths. A computationally efficient circuit-equivalent modeling approach based on the electric-field integral-equation (EFIE) formulation is employed to simulate the highly dispersive behavior of nanowires at short wavelengths. The proposed approach can be used both for frequency-domain and for time-domain EFIE formulations. In comparison with widely used full-wave solutions achieved through the finite-difference time-domain method, the circuit-based EFIE formulation results in a sharp reduction of the computational resources while retaining high accuracy.
