Title: Kazuhiko Takano: Innovator in Leaky Cable Technology

Introduction

Kazuhiko Takano, an inventive mind hailing from Sakura, Japan, has made significant contributions to the field of electromagnetic wave propagation through his innovative designs in leaky cables. With a commendable record of two patents, Takano's work showcases his commitment to advancing technology in telecommunications.

Latest Patents

One of Takano's notable inventions is a leaky cable that features at least one slot row for propagating electromagnetic waves that have been diffracted backwards. This unique leaky cable comprises a central conductor and an outer conductor with a rectangular cross-section encasing the central conductor. The outer conductor has two parallel surfaces and incorporates a slot row fashioned in the first direction, which includes multiple slots designed to generate a leaky electromagnetic field. Between the central and outer conductors lies an insulator, and the cable is designed such that the width of the rectangular cross-section is less than half the wavelength of the electric signal being transmitted.

Additionally, Takano has developed a leaky coaxial cable characterized by a series of slots strategically arranged in a string shape along the outer conductor. These slots are tailored to create an electromagnetic field leak, with the pitch intervals of the slots being periodically modified in the axial direction. The periodic alterations can follow patterns dictated by sinusoidal or quadratic functions, allowing for customizable electromagnetic wave propagation.
