Abstract
We investigate the dynamics and pattern formation properties of a fluid interface subjected to spatially nonuniform parametric forcing. This is explored experimentally, by horizontally vibrating a container of fluid to create an effective parametric forcing mechanism localized near the endwalls, and theoretically, using appropriate model equations. Experimental results demonstrate the prevalence of so-called subharmonic cross-waves and reveal several new and interesting properties, including a preferred orientation other than 90 degrees and a tendency to form domains of distinct patterns. Some theoretical explanation for these properties is provided and the importance of resonant interactions made clear.
