             abstract = "Continuous nonlinear transmission lines (NLTLs), also known as 
                         gyromagnetic lines, consist of ferrite-based magnetic cores biased 
                         by an external magnetic field. Over the past years, many 
                         analytical and experimental studies have predicted the rise time 
                         reduction of the input pulse to the range of a few nanoseconds or 
                         even hundreds of ps experimentally observed in such gyromagnetic 
                         lines. This effect, known as pulse sharpening, is investigated in 
                         this paper built on a model based on a periodic structure of 
                         inductivecapacitive cells in series with magnetization-driven 
                         voltage sources expressed by the one-dimensional form (1D) of the 
                         LandauLifshitzGilbert (LLG) gyromagnetic equation. We explore the 
                         model through parametric study under various inputpulse parameters 
                         to understand the physics behind the ferrimagnetic material 
                         responses. Moreover, the numerical results obtained from 
                         computational simulations using Mathematica (v. 12.1) show how the 
                         line parameters (input voltage, damping constant, saturation 
                         magnetization, and length) affect the sharpening effect, which is 
                         quantified by the switching time. Our results on ferrite-loaded 
                         coaxial lines have confirmed many results found in the literature. 
                         We validated with a good agreement the proposed model with the 
                         result obtained by Dolan in 1993 using the same 1D form of the LLG 
                         equation, thus showing that the model proposed here is suitable to 
                         quantify the sharpening effect produced by a gyromagnetic NLTL.",
