Dynamic Wireless Power Transmission has attracted attention in the research area due to its safety, convenience, and automation. However, the major limitation in achieving this vision is its working distance. In this paper, the metamaterial (MM) based transmitter WPT with zero permeability is presented and compared with an inductive WPT system. The comparative simulations and experimental investigations validate the effectiveness of the proposed design. The system efficiencies are determined at the distances of 8 cm, 11 cm, and 16 cm between the transmitter and receiver (SAE J2954) with an operating frequency of 20 kHz. The power transfer efficiency (PTE) of the WPT system using an inductive transmitter and the WPT system using an MM-based transmitter is shown as 85/87%, 65/70%, 45/65%, respectively. The PTE of the MM-based transmitter is 64% higher than an inductive transmitter at a 16 cm distance. The robot without a battery moves dynamically along the track with the MM-based transmitter underneath. The results show that the power transfer efficiency of the MM-based transmitter is considerably higher than that of the inductive transmitter.
