Then: Symposium On The Biological Effects And Health Implications Of Microwave Radiation

A Revival Of The Microwave-Biology Field?
In the ten years preceding the last Tri-Service Symposium (1960) on the “Biological Effects of Micro-waves,” a considerable community of researchers participated in the study of interaction of microwaves with biological systems, particularly animals and man. Military standards were confirmed at 10 mw/cm2 maximum permissible exposure levels based on...

Towards the Validation of a Commercial Hyperthermia Treatment Planning System

Recent developments have reinvigorated clinical investigations of hyperthermia (HT) as a viable adjuvant treatment in the fight against cancer. Researchers are placing a greater emphasis on multi-modal approaches that include mild temperatures (40° to 43°C) and standard therapies like radiation and chemotherapy, than on achieving higher temperature treatments (43°...

Link Budget Calculation for UHF RFID Systems

This article provides the basic concepts necessary to perform a link budget analysis of passive UHF RFID systems. Unlike conventional wireless communication systems, there are two intrinsic characteristics that determine the link budget in UHF RFID sys...
Radio frequency identification (RFID) is an automatic identification method that relies on storing and remotely retrieving data using devices known as RFID tags or transponders. RFID systems with a variety of radio frequencies and techniques have been introduced. 1 Among them, the ultra-high frequency (UHF) band passive RFID system...

Wideband Dual-top Loading Monopole Antenna

In this article, a low profile, wideband, dual-loaded monopole antenna with a ring-shaped plate is presented. The ring-shaped plate in the ground plane is used to enhance the impedance matching and to increase the antenna gain, resulting from a low rad...
Monopole antennas are used in mobile communications. A monopole antenna is a very simple and efficient radiating element. 1 It is well known that the smaller the size of the antenna, the lower its efficiency and narrower its bandwidth (a few percent). 2 A 36 percent bandwidth enhancement of...
