High frequency fields
High frequency electromagnetic fields cover the frequency range from 100 kHz to 300 GHz of the electromagnetic spectrum. In general they are distributed by an antenna. They are able to distribute energy and information over a great distance.
Because high frequency electromagnetic fields are used for multiple purposes (e. g. radio and TV broadcast, mobile communication, cordless phones, wireless LAN and bluetooth connections) we are surrounded by a large number of different emitting facilities operating at various transmitting powers and frequencies.
