    Reviews activities in the field of propagation research, in the 1990s, in Japan. The authors focus only on propagation studies related to radio communications; activities in the field of remote sensing are outside the scope of this review. Since Kagoshima and Shiokawa (1992) included a short review of research activities in this field, in the period from 1989 to 1991, the emphasis of the present r... View full abstract»

    The present survey paper summarizes radio-propagation measurements and models for emerging wireless personal-communication systems. Both indoor and microcell-propagation environments are considered, and the problem of RF penetration into buildings is identified as an important area of research for emerging wireless-communication systems.<> View full abstract»

    Describes a compact HF-antenna accessory, designed for use with book-sized portable receivers. It converts the receiver for sky-wave-direction finding (DF), co-channel-interference reduction, and radio-frequency-interference (RFI) location, while being hand-carried by the user. When the system is operated in the DF mode while in motion, site-related errors in line of bearing (LOB) can be reduced b... View full abstract»

    For well over a decade, research groups around the world have been investigating photonic devices for use in antenna, phased-array, and electromagnetic-field-sensor systems. Proposed applications include EMC monitoring, EMP measurements, anechoic-chamber calibration, novel antenna and array designs, remotely located antennas, and smart skins. Photonic antenna links allow immunity from electromagne... View full abstract»

  • Analysis of the radiation resistance and gain of a full-wave dipole

    The full-wave-dipole antenna is very seldom used in communication systems, and yet this type of antenna offers a very high gain. This is due to the high input impedance for the center-tap feeding-point antenna. The analysis of short-length and half-wavelength dipole antennas has been reported, in great detail previously, in texts. However, an analysis of the full-wave dipole antenna has not been d...

    The accuracy and stability of transient numerical methods in electromagnetics is an important consideration, for which an analytical measure is necessary. Of the several approaches commonly used to indicate accuracy of numerical methods, the modified equation of Warming and Hyett [1974] is examined, for several finite-difference and finite-element time-domain methods. In the method of Warming and ... View full abstract»
