Title: Yoshiaki Tarusawa: Innovator in Electromagnetic Measurement Technologies

Introduction

Yoshiaki Tarusawa is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of electromagnetic measurement technologies, holding a total of 13 patents. His work has been instrumental in advancing the understanding and application of radio wave interactions with human-like models.

Latest Patents

Among his latest patents is an "Apparatus for measuring absorbed power." This innovative device includes an electromagnetic field probe that is fixedly mounted within a head simulation phantom. The phantom simulates the configuration and electromagnetic characteristics of a human head. The apparatus measures the strength of an electric or magnetic field from externally irradiated radio waves and estimates the power absorbed by the head based on these measurements. The head simulation phantom can consist of either a solid dielectric or a liquid dielectric, both designed to replicate the characteristics of a human head.

Another notable patent is for a "Radio communication terminal." This terminal is designed to be in close proximity to or integrated within electronic equipment. It features a receiver connected to a receiving antenna and an interference canceller that removes radiated noise components from the received signal. The interference canceller includes a radiated noise predictor that generates a pseudo interference signal to effectively cancel out the noise.
