Summary:
Recently, a rapid progress has been made in the area of wireless sensor networks to gather physical data and to control natural environment [1]. Sensor devices are usually distributed on dessert, hilly and sea surfaces. They are assumed to be random rough surfaces, and thus it is important to investigate propagation characteristics of electromagnetic waves traveling along rough surfaces and its statistical properties above rough surface since the sensor devices located on rough surface are much influenced by scattered waves from random rough surface. In this paper we investigate statistics of electromagnetic field above random rough surfaces from a view point of experiment and numerical simulation based on the Finite Volume Time Domain (FVTD) method [2]. Experiments using a concrete rough surface model are carried out in a radio anechoic chamber. Using a probability paper, we consider whether the statistics of electromagnetic fields agree with a Nakagami-Rice distribution which is well known as statistics of electromagnetic fields in urban area.
