In this paper, a novel Micro Electro Mechanical System (MEMS) based cantilever beam of cross section (400×150×1)μm is presented for the detection of Metronidazole (MZN) which can be used in food processing industry to detect its toxicity level in meat. MZN is a drug that is proven to be carcinogenic if used as feed addictive for cattle breeding or aquafarming. Molecular imprinted Gold cantilever beam...
A compact electric field generator has been explored to transmit electric energy wirelessly to piezoelectric components by using the electric resonance of a flat spiral coil antenna-like structure and a capacitor in series. In the flat spiral coil antenna-like electric field generator, the ac electric field is transmitted wirelessly to the piezoelectric plate placed in a plane perpendicular to the...

This paper presents an analysis for the resonant frequencies and its various harmonics of a nearly Circular Annular Ring Microstrip Antenna (ARMSA) with and without air gaps and superstrate loadings. This ARMSA is studied for various radii of the inner and outer radiating circular edges of disc. Three such nearly circular ARMSA are analyzed with an Aspect Ratio of 0.98. By diagonal feeding at the...
This paper presents the design of an ultra wide band (UWB) antenna with CPW-fed. The antenna has been designed on FR4 substrate ??r = 4.3 and thickness 1.53 mm. The antenna has been fabricated and tested using VNA. The experimental results of this antenna offer ultra wide bandwidth from 2.86 GHz to 14.38 GHz.

Microstrip antenna consists of a radiating patch on one side of dielectric substrate which has a ground plane on the other side. The antenna element it self may be square, rectangular, circular, triangular etc and may have more than one feed. An experimental study of dual band characteristics of single layer rectangular microstrip antenna is presented. For feeding of the antenna direct microstrip...
An approach to modeling a resonant meanderline attenuator of helical slow-wave structure for a travelingwave tube is presented that uses eigen-mode solver in HFSS. The dispersion, interaction impedance and attenuation characteristics of the structure in the presence of the resonant attenuator were predicted using the model and were validated against experimental results, published elsewhere.
