Abstract
A phase lag phenomenon in which waves are delayed in transmission through a permeable breakwater was considered in an approximate calculation method using the superposition principle of Sommerfeld. Experimental verifications were carried out for a semi-infinite permeable breakwater. In addition, a field observation of wave height distribution around a small detached breakwater is reported.
