A conventional wire communication system communicates between powered terminals via a main unit. In this system, the main unit communicates with the powered terminals by changing the voltage signal between positive and negative. The powered terminal communicates with the main unit using the reply current signal. Because this system is used for on-off control, the communication speed is slow. Therefore,...

To evaluate the performance for non-contact testing of large scale integrated circuits, we observed various simple test circuits after build-in defect using laser THz emission microscope (LTEM), which detects THz wave amplitude emitted from semiconductor test circuits excited by focused ultrafast laser pulses.

We fabricated a photonic crystal superlens and clearly observed the focusing of light by the negative reflection, for the first time. It well agreed with the dispersion surface analysis and the FDTD simulation.
