                         behavior are essential for use in capacitive nonlinear 
                         transmission lines (NLTLs) for RF generation. NLTLs have a great 
                         potential to generate soliton waves for high-power microwave 
                         applications in mobile defense platforms and satellite 
                         communications. In this paper, the dielectric properties of a 
                         piezoelectric capacitor based on lead-zirconate-titanate (PZT) was 
                         characterized in a broadband frequency range from 10 MHz to 1 GHz 
                         for use in NLTLs. Three commercial ceramic capacitors made of 
                         barium titanate (BaTiO\₃) were also assessed for comparison 
                         with the PZT capacitor. The characterization of materials 
                         consisted of measuring the relative dielectric constant (real and 
                         imaginary parts) as function of the applied voltage and frequency 
                         to calculate the loss tangent of the material. The results showed 
                         that PZT material has a better performance for use in NLTLs than 
                         barium titanate because of its lower losses. As discussed here, 
                         however, the use of PZT and barium titanate-based materials in 
                         NLTLs are compromised by the self-resonant frequency of the 
                         capacitors because of the inherent parasitic inductance associated 
                         with the capacitor at high frequencies.",
