Purpose: One of the most important issues regarding radio frequency electromagnetic fields (RF‐EMF) is their effect on genetic material. Therefore, we investigated the cytogenotoxic effects of 900 MHz radio frequency electromagnetic fields (RF‐EMF) and the effect of a recovery period after exposure to RF‐EMF on bone marrow cells of immature and mature rats. Materials and methods: The immature a...

The most common used methods for water disinfection were chemicals like chlorine, ozonation, ultraviolet radiation, membrane processes, etc. Water disinfection using irradiation techniques is new in water treatment industry which has been developed recently. The aim of the present study was to investigate radio frequency (RF) efficiency for the inactivation of total coliform (TC), fecal colifor...

Most applications for radio frequency/microwave (thereafter called RF) transistors had been military oriented in the early 1980s. Recently, this has been changed drastically due to the explosive growth of the markets for civil wireless communication systems. This paper gives an overview on the evolution, current status, and future trend of transistors used in RF electronic systems. Important ba...

Broadband Wireless Access has occupied a niche in the market for about a decade, but with the signing of the 802.16d standard it could finally explode into the mass market. Intel’s baseband transceiver chip is flexible enough to accommodate Radio Frequency Integrated Circuit (RFIC) architectures of today and the future. With the emergence of this standard an ecosystem is developing that will al...

Radio Frequency (RF) channels and networks are often used to carry information whose existence may be necessary for organizational operation, or whose content must remain inaccessible to third parties. Cryptographic solutions are commonly employed to render the information on RF links unintelligible to unauthorized recipients, though the existence and nature of the links themselves may assist a...

Due to the high attenuation of radio frequency (RF) signals in underground mines and the statutory power restriction of communication gadgets especially for coal mines, the wireless communication systems have restricted applications in the underground mines. The paper discusses different radio frequency communication techniques being employed for Indian underground mines. Experiments were condu...

Motion and intrusion detection are often cited as wireless sensor network (WSN) applications with typical configurations comprising clusters of wireless nodes equipped with motion sensors to detect human motion. Currently, WSN performance is subjected to several constraints, namely radio irregularity and finite on-board computation/energy resources. Radio irregularity in radio frequency (RF) pr...

A reduced graphene oxide (RGO) based glucose sensor using a radio frequency (RF) signal is demonstrated. An RGO with outstanding electrical property was employed as the interconnector material between signal electrodes in an RF electric circuit, and it was functionalized with phenylbutyric acid (PBA) as a linker molecule to bind glucoses. By adding glucose solution, the fabricated sensor with R...

Wireless communication technology such as cellular and wireless local area network (WLAN) systems have grown rapidly and generated various competing transmission formats. In the need of seamless communication across incompatible radio standards, software defined radio (SDR) concept has received much attention among researchers working in mobile and personal wireless communications. SDR is a tec...
