The effects of microwave interference on the operational parameters of individual MOSFET devices on CMOS wafers were studied as microwave power and frequency were varied. The study used direct injection of microwave power into the device terminals, and the output characteristics were measured with and without the microwave interference. The study showed that injected microwave power significant...

today special attention has been paid to the microbial quality of medicinal plants.one of the operations in order to maintain the quality of plants is drying which may also affect the quantity and quality of the essential oil. in order to evaluate drying process effect in peppermint,the experiment was conducted in randomized complete block design with 4 treatments and 3 replications. the treatm...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

A novel type of power divider, featuring arbitrary power ratio and arbitrary ripple level, is proposed. This divider consists of a two-port filtering structure connected to a circulator and is straightforwardly designed using microwave filter synthesis techniques. An example is provided, with low-pass domain synthesis and experimental divider demonstration at the Xband, after low-pass to bandpa...

Having combined the advantages of ground-based interferometric radar and Global Position System (GPS), a microwave radar with transponder for three-dimensional displacement monitoring method has been proposed. In this system, the active reflector ensures the long measurement distance at low antenna radiation power; the transponder provides the total solutions to antenna microwave leakage and mu...

Cells of human buccal epithelium of 6 male donors were exposed to microwave radiation (frequency f=36,64 GHz, power density E=10, 100, and 400 µW/cm 2). Exposure time in all experiments was 10 seconds. Heterochromatin was stained by 2% orcein in 45 % acetic acid. The stainability of cells with trypan blue (0,5 %) and indigocarmine (5 mM) after 5 min of staining was investigated. Irradiation ind...

* Work supported by the US Department of Energy. In this paper we consider the preliminary designs of three-cavity microwave circuits for coaxial gyroklystrons. These tubes are predicted to produce over 100 MW of power in 1 μs pulses in Xand Ku-Band for linear collider applications with efficiencies exceeding 40% and gains above 50 dB. In particular, we examine the effect of first and second ha...

The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...

OBJECTIVES To retrospectively collect data on patients with burn injury due to hot depilatory wax. To investigate the effect of varying microwave output power on wax temperature. To determine whether instructions provided by manufacturers allow safe domestic use. METHODS Data from the RAH burns database was collected for patients with wax-induced burns between January 1991 and January 2010. W...

In this paper, we present the concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. A wireless power transmission using microwave is a system which contains satellite based solar power system (SPS), microwave generator, microwave transmitter (magnetron) and microwave rece...
