Abstract: Environmental Electromagnetic Compatibility n the last decades, there have been a number of significant advances in many areas of Environmental Electromagnetic Compatibility (EEMC).Valuable contributions of the electromagnetic field analysis related to the antennas, lines and cables, bioelectromagnetics, broadband EMI, lightning, etc. have been presented in many conferences and also reported in many acclaimed international journals.These studies, which have been carried out by numerical simulation and experimental techniques, provide the scientific knowledge for the electromagnetic phenomena in general and also give scientific background and improvement in electromagnetic and thermal dosimetry, design and protection of electrical and electronic equipment.Therefore, the Guests Editors enthusiastically accepted the proposal of prof.N. Rozic, Editorial Chair of Journal of Communications, Software an Systems (JCOMSS), to edit a Special Issue on Environmental Electromagnetic Compatibility by collecting some important recent contributions achieved by prominent researchers in this area.Initial idea was to edit an issue on Mobile and Wireless Communications, but we finally extend aims and scopes of this particular issue to many other areas of EMC and decide to produce a special issue on Environmental Electromagnetic Compatibility (EEMC).
