... Abstract Wave diffraction is a fundamental problem in wave theory. At present, a lot of researches have been conducted on the diffraction of the relatively simple port arrangements such as a single jetty, a double jetties, and an island embankment. However, the planar arrangement of many...

... for fishing and tourism. Thus, the wave behavior inside and outside the lagoon is worthwhile to study. Generally speaking, due to the sheltering of island and reef flat, diffraction plays the most important role when waves enter the lagoon. Wave diffraction has been widely studied in recent decades(Abohadima...

... and λ is the wave length), wave diffraction is important and should be considered. A superposition eigenfunction expansion method was used by MacCamy and Fuchs (1954) to obtain a linear solution, based on the assumption that the incident wave has a small steepness. For the case of waves acting upon...

... Abstract Infragravity waves observed inside a harbor may consist of free waves not only propagated from offshore but also generated (released) at harbor entrance due to reduction of wave groups by diffraction and breaking. In this study, numerical simulations of both wind and infragravity wave...
