Transmission loss and radiated electric field characteristics of transmission medium for ubiquitous network

Transmission loss and radiated electric field characteristics of the pipe-based transmission line as new transmission medium are calculated by using the method of moment, and it is clear that the calculated values almost agreed with measured values. In addition, it is confirmed that the pipe based transmission system can obtain dynamic range of about 69 dB and realize secure transmission, even if the radiated electric field from the pipe-based transmission line comply with the limit of the information technology equipment specified by VCCI.
