“…A background study concerning nonlinear guided waves in media with Kerr and Kerr‐like nonlinearities can be found in Smirnov and Smolkin (2018), Smolkin and Shestopalov (2017), Smolkin and Valovik (2015), and Smirnov et al (2019). In papers (Smirnov et al, 2014; Smolkin, 2017; Smolkin et al, 2017; Smolkin & Shestopalov, 2015; Smolkin & Valovik, 2012) numerical study of the surface wave propagation in layered nonlinear dielectric and metal‐dielectric waveguides is performed. Numerical results are obtained with the help of a version of the shooting method (see, e.g., Smirnov et al, 2014; Smolkin & Valovik, 2013).…”
