A novel approach utilizing one‐dimensional (1D) wave equation based finite difference time domain (FDTD) formulations for Lorentz‐type Epsilon‐Negative (ENG) medium is developed. To demonstrate the validity and accuracy of the formulation, reflection of a plane wave normally incident at free space—ENG interface is compared with the analytical solution. Moreover, propagation characteristics of Lorentz‐type ENG medium is investigated using the FDTD formulations both for wave equation and Maxwell's curl equations in 1D case. Comparisons of memory and computational time requirements of both formulations are given. © 2016 Wiley Periodicals, Inc. Int J RF and Microwave CAE 26:304–310, 2016.
