             abstract = "Ferrite-charged nonlinear transmission lines (NLTLs) have been 
                         used as electromagnetic shock lines in applications that require 
                         pulses with extremely fast rise times. Subject to an intense 
                         external magnetic field (20-40 kA/m), these lines can generate 
                         microwave radiation generally in L-band (1-2 GHz) and are known in 
                         this case as nonlinear gyromagnetic lines. Due to its wide 
                         applicability in the RF area, such as electronic warfare (in 
                         defense) or high power beam modulators (in industry), there is 
                         growing interest in the study of these lines, especially using 
                         finite difference time domain (FDTD) simulations to predict some 
                         important line parameters, such as the rise time of the output 
                         pulse and the frequency generated. The FDTD method is based on the 
                         nonlinear behavior of the magnetic material that fills the line as 
                         the current pulse propagates, inducing RF oscillations due to the 
                         precession of the ferrite's magnetic moments, described 
                         mathematically by the Landau-Lifshitz-Gilbert equation (LLG). 
                         Thus, this work presents a one-dimensional numerical modeling and 
                         simulation (1D) study to describe the behavior of these lines, 
                         which operate in the TEM mode. The numerical simulations were 
                         obtained using the joint solution of the transmission line 
                         equations and the gyromagnetic LLG equation in the publicly 
                         available software OCTAVE.",
