-This study presents a linearization technique for transducers by using software solutions programmed into a microcontroller. Existing data acquisition systems linearize nonlinear transducer characteristics in real time using analog linearizing circuitry, which are susceptible to errors due fluctuations in power supply voltage, temperature, and interference from correlated and uncorrelated nois...

Microwave detection of the Shubnikov-de Haas (SdH) effect as a contact-free characterization technique for different types of two-dimensional semiconductor structures is explored in the low magnetic field region. The detection technique and the data analysis are described. The character and relevance of the single-particle relaxation time that can be detected by this technique are distinguished...

Magnetic circular dichroism is a powerful spectroscopic tool for the assignment of optical resonance lines. An extension of this technique, microwave-modulated circular dichroism, provides additional details, in particular information about the orientation of optical transition moments. It arises from magnetization precessing around the static magnetic field, excited by a microwave field, in cl...

We discuss two new observational techniques that use observations of the Cosmic Microwave Background (CMB) to place constraints upon the mass, distance, and size distribution of small objects in the Kuiper Belt and inner Oort Cloud, collectively known as Trans-Neptunian Objects (TNOs). The first new technique considers the spectral distortion of the isotropic, or monopole, CMB by TNOs that have...

Additive manufactured (AM) metals are a subject of much interest for their performance in passive microwave applications. However, limitations could arise due to artifacts, such as surface texture and/or roughness resulting from the manufacturing process. We have, therefore, adopted parallel plate resonator accurate measurement resistance flat metal plates, allowing current flow two orthogonal ...

We report the complex microwave conductivity, σ = σ 1 − iσ 2 , of Na-DNA powders, which was measured from 80 K to 300 K by using a microwave cavity perturbation technique. We found that the magnitude of σ 1 near room temperature was much larger than the contribution of the surrounding water molecules, and that the decrease of σ 1 with decreasing temperature was sufficiently stronger than that o...

We have developed a very sensitive, highly selective, non-destructive technique for screening inhomogeneous materials for the presence of superconductivity. This technique, based on phase sensitive detection of microwave absorption is capable of detecting 10(-12) cc of a superconductor embedded in a non-superconducting, non-magnetic matrix. For the first time, we apply this technique to the sea...

Microwave water disinfection is a rapid purification technique which can give billions of people access to clean drinking water. However, better understanding of bacterial recovery after microwave heating over time is necessary to determine parameters such as delayed bacterial growth rates and maximum bacterial yields. Mathematical models for Enterococcus faecalis recovery after microwave treat...

Continuous microwave processing system is one of the pasteurization/sterilization techniques that offer good potential for high quality, reduced process times and energy as compared with conventional techniques. The overall goal of these studies was to process and preserve the fruit and vegetable juices through continuous flow of microwave heating system. Two categories of 10 blends were prepar...
