Abstract

Model human hands (902) for use in electromagnetic (e.g., microwave and RF) testing comprise a skeleton (1200, 104) of dielectric tubes (142, 148, 166, 170, 174, 178, 206, 208, 210, 1202, 1212, 1214, 1216, 1228, 1230, 1236, 1240, 1242, 194, 195, 196) inside a glove (908) that is filled with a fluid that has electrical properties that match that of a typical human hand at a particular frequency. According to certain embodiments the model hands comprise thumbs (193, 1236) that are located out of a plane of palms of the model hands. According to one embodiment the dielectric tubes are pivotally coupled to each other and biasing means (181,702) are provided to bias the hand into a gripping position so that the model human hand is able to grip different types of wireless communication devices (802) in different ways.
