The cookie-cutter 'chevron' structures that cut into the rear of Boeing's 787 airliner's engine, basically lead to destructive interference by mixing the emerging hot air blasting out of the jet core with the draggy eddy currents generated as the engine bites into the airflow around the engine This decreases the engine noise by 15 decibels when the airliner is at the airport.
It also appears that the geometry of geological structure (synform) has led to destructive interference (a cancelling) of the magnetic signal in the centre of the structure, resulting in an apparently weak or absent response despite drilling confirming that the magnetite gneiss occurs relatively close to the surface in this area.
