SEMW theory　(solitary electromagnetic wave theory)

A new theory developed by ICAST to elucidate the mechanism of occurrence and behavior of electromagnetic waves in the electrical circuit. To illustrate the behavior of the electromagnetic wave generated in the electric circuit, this theory does not use an approximate calculation, such as by using conventional methods, such as Fourier transform or equivalent circuit. This theory has been described it in more substantive based on the "non-linear theory" and "Electrical Engineering" and "electromagnetism", using the concept of "soliton" is completely single solitary wave. This theory is being proven to be a significant part by the Measured data of experiments, simulations by SPICE, and development of new calculations which ICAST has made.

LILL　(low impedance lossy line)

On-board LILL

LILL is one of the technology that has been developed based on SEMW theory to control the electromagnetic wave in electrical circuits. LILL has the function of reflecting the electromagnetic waves, and contributes to, such as suppression of electromagnetic noise on the power supply side and faster circuit mainly. An Electromagnetic wave necessary for the excitation of voltage of the circuit is generated by a switching. And voltage is excited completely by an electromagnetic wave is transmitted to the signal side from the switch completely. But Half of the electromagnetic waves generated by the switching is propagated to the power supply side once, and reflected back on the power, the voltage is completely excited for the first time it is transferred to the signal side, the circuit starts to operate. According to the calculation based on this theory, this time difference, the half electromagnetic wave is reflected back at power supply after propagating power supply side, coincides with the actual time difference until the excitation voltage from the switching. Accordingly, if you build a structure that reflects the electromagnetic waves right next to the switch of power supply side, you will reduce this time difference as possible, the required voltage will be excited after the switching instant. We call this structure reflects electromagnetic waves "LILL". There are three types of LILL is in that we developed, that is to say, type to be installed as a component on the board (on-board type), type to be built directly into the board (built-in type), type to be built directly into the LSI chip (on-chip type).

MILL　(matched impedance lossy line)

SEMW on the MILL

MILL is one of the technology that has been developed based on SEMW theory to control the electromagnetic wave in electrical circuits. MILL has the function to absorb electromagnetic waves, mainly contributes to such as the suppression of the circuit's malfunction and electromagnetic noise in signal side. By the switching of hundreds of millions of LSI, huge number of SEMW is generated. These SEMW continues to propagate everywhere in the circuit, Until completely consumed as the energy of the excitation voltage. In the process, several SEMW may leak into adjacent lines that are not directly connected (cross talk), or may leak to the outside of equipments, devices, or circuits. The structure while absorbing these "noisy" SEMW, to supply the energy required for the excitation voltage circuit is called "MILL" to us. Accordingly, if you build a structure of MILL right next to the switch of signal side, you will achieve a more complete suppression of electromagnetic wave leakage. There are three types of MILL is in that we developed, that is to say, type to be installed as a component on the board (on-board type), type to be built directly into the board (built-in type), type to be built directly into the LSI chip (on-chip type).
