- Abstract
- This study verifies the feasibility of surface-wave communication as a solution to the severe attenuation and multipath fading encountered by free-space wireless systems in metallic environments. Surface-wave characteristics on dielectric-coated metal surfaces are analyzed in terms of field distribution and attenuation with respect to dielectric thickness and frequency. Experiments conducted in a structure emulating a watertight door show that placing a dielectric layer on the metal surface increases the received signal strength by about 5 dB and improves throughput by more than fourfold compared with the case without the dielectric layer. Additional experiments comparing surface-wave and free-space communication in the same ship-like structure demonstrate that surface-wave communication achieves approximately a 7 dB increase in received signal strength and more than a 15-fold improvement in throughput relative to free-space propagation. These results confirm that surface-wave techniques can significantly enhance wireless coverage and reliability inside dense metallic structures and provide practical insights for future industrial wireless communication system design.
