A New Type of Robot System for High-Resolution Field Mapping

This paper deals with a high-resolution field scanner that accomplishes a measurement of the field distribution inside a gigahertz transverse electromagnetic cell. Further, simulations have been carried out in order to back up measurement results. The field inside the cell has been measured under different loading conditions for different frequencies. Each loading condition distorts the field inside the cell differently. In order to show these distortions, a special flexible scanning robot has been developed and constructed. It moves an isotropic $E$-field sensor while distorting the field very little due to its nonmetallic materials.
