概要

Along the electro-magnetic wave flows of 100kHz LF band in the vicinity of a triangular mountain model, the phase fluctuation has been calculated and pictured by means of the Finite Element Method. It is shown that conspicuous phase lag on the wave coming slope of the mountain has taken place and on the contrary, some phase restoration on the against side slope has been recognized within λ/2 from the top of the mountain. This result well resembles phenomenon which was observed at the sea coast when the 100kHz LF band electro-magnetic wave went across the boundary from the land of low conductivity to the ocean.
