What is it about?
Novel solitary electromagnetic wave (SEMW) theory is only for switching mode circuit (SMC) including digital circuit. Transmission loss that is harmful in analog circuit was verified for the first time to be so beneficial to SMC by this theory. Lossy line (LL) technologies were developed based on this fact.

Why is it important?
Design and analysis of SMC become speedy and precise by SEMW theory. Voltage shape is kept till next switching even if SEMW is attenuated. Electromagnetic interference including crosstalk and signal bounce can be suppressed perfectly by applying LL technologies to SMC. Clock frequency of MPU is possible to be 2-digit increase by applying LL technologies on MPU. In addition, bit per second (bps) of data transmission will increase 2-digit by applying LL technologies on PCB and by using a hundred of insulated thin wires in parallel.
Perspectives
I hope this article will influence to researchers and engineers about SMC. But they will have more interest to SEMW theory and lossy line technologies if they actually examine and use commercialized lossy line product. Commercial grade high-performance LL components for power line and signal line without expensive material and process are already developed. We would like to commercialize these LL components as soon as possible. We need business partners for achieving this plan. We sincerely hope that many persons or companies find this article and they collaborate to our plan.

Lossy Line Technologies for Digital Circuit Based on Solitary Electromagnetic Wave Theory
Applied physics article. According to the solitary electromagnetic wave (SEMW) theory, it is estimated that the transmission loss is useful to improve the performance and stabilizing the operation of the switching mode circuit (SMC) including the digital circuit. The validation result of the excellent effect of transmission loss at the digital circuit by experiment and calculation are shown in this paper. The lossy line technologies will solve many problems about the wiring of system on a chip (SoC), printed circuit board (PCB) or information technology (IT) equipment. As the result, it will help the great progress of IT in the future.
Analysis of On-chip Interconnects in Basing on Solitary Electromagnetic Wave Theory
Suitable material for on-chip interconnects has been believed to be the low resistive conductor by basing on the AC circuit theory of engineering. On the other hand, according to the solitary electromagnetic wave (SEMW) theory, it is clarified that the lossy transmission line is contrarily suitable for the signal line of the switching mode circuit (SMC) including the digital circuit. Therefore, the effect when the wire with relatively high resistance is used to the signal interconnects was analyzed based on the SEMW theory. Here, the low impedance lossy line (LILL) technology is applied to conventional power mesh of on-chip interconnects.
Solitary Electromagnetic Theory and Its Application
Applied physics article. Development process of novel solitary electromagnetic wave (SEMW) theory, outline of it, and some application examples of it about the digital circuit that is the typical switching mode circuit (SMC) are presented. SMC consists of switching transistor, power line, and signal line. It is expected that the electromagnetic wave will be generated by the switching transistor. Therefore, the current of switching transistor was analyzed in accordance with semiconductor physics. Applying non-linear wave physics and electromagnetic physics to this result, SEMW theory was developed. It will supplement the conventional electromagnetic physics and will help the great progress of IT in the future.
