Non-invasive determination of plant biomass with microwave resonators

Non-Invasive Determination of Blood Glucose Levels by Optical Waveguide

Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of ne...

Chaos in Microwave resonators

Up to about 1990 the quantum mechanics of classically chaotic systems, shortly termed ‘quantum chaos’, was essentially a domain of theory [1]. Only two classes of experimental result had been available at that time. First, there were the spectra of compound nuclei giving rise to the development of random matrix theory in the sixties of the last century, and second the experiments with highly ex...

An Overview of Microwave Bandpass Filters with Capacitive Coupled Resonators

This paper presents a summary of several bandpass filters all consisting of resonators coupled only by capacitive coupling. The basic filter’s configuration with asymmetric inductors is explained in detail as well as its modifications with asymmetric capacitors. The filter’s design process is undemanding due to the filter’s simple configuration, while its compact size makes it suitable for inte...

Experimental study of generic billiards with microwave resonators

In this work we study the eigenstates and the energy spectra of a generic billiard system with the use of microwave resonators. This is possible due to the exact correspondence between the Schrödinger equation and the electric field equations of the lowest modes in thin microwave resonators. We obtain a good agreement between the numerical (exact) and experimental eigenstates, while the short r...
