This paper proposes a new application of skin effect suppression technology [1]–[4] for long wiring on high-speed & low-delay I/O board (typical wiring length; 200 to 1000 mm). This proposal will overcome the difficulty to further reduce the transm

A novel synthesis method for a class of time-domain passive fllters that compensates for waveform distortion caused by frequency dependencies of the transmission properties of signal propagation paths, is formulated. The method is based on the linear

After a report on strange electromagnetic resonances emerging in an isotropic paraelectric Menger sponge (MS) now known as a photonic fractal, vigorous studies began to reveal their properties. However, the mechanics of how the resonances occur is st

Menger's sponge (MS) is a kind of three-dimensional fractal structure. To analyze non-resonant electromagnetic properties of MS composed of isotropic paraelectric material, a novel, high-speed computation method employing simple recursion equations i

Multilayered filters with a dielectric distribution along their thickness forming a one-dimensional quasi-fractal structure are theoretically analyzed, focusing on exposing their resonant properties in order to understand a dielectric Menger's sponge

We propose an optoacoustic airborne ultrasonic sensor consisting of a 633-nm He-Ne laser, an Si PIN photodetector, and a sensor head. The device has a sensitivity of 92.7 dB SPL (Sound Pressure Level) for acoustic signal inputs of single 40-kHz pulse
