Perlite or pearl stone is a natural glass which has formed by rapid cooling of viscous lava or magma. Perlite is mainly composed of silica, aluminum, potassium and sodium. In this experiment, perlite was used as a low-cost source of Si and Al to synthesis of sodalite zeolite using the alkaline hydrothermal treatment. A statistical Taguchi design of experiments was employed to evaluate the effec...

The dielectric and relaxation parameters of a binary system of edible oils, containing unsaturated fats namely mustard oil and coconut oil/ground nut oil/linseed oil in different proportions by volume are measured at different frequencies and a constant temperature (40°C). It is realized that at the given temperature, the dielectric constant of prepared samples at microwave frequency increases ...

This study presents a global electromagnetic optimization technique using Taguchi’s method [1] and its applications in microstrip filter designs. Microwave filters are widely used in telecommunication equipments. Although filters built with lumped elements can realize the desired frequency response, it is difficult to control the lumped elements’ properties in the microwave band. Therefore pass...

Microwave-induced thermal acoustic imaging (MITAI) is a promising early breast cancer detection technique, in which image construction is based on thermo acoustics signals generated by the illumination of microwave pulses in tissue. In this work we have performed a microwave induced thermal acoustic signal generation simulation study using Comsol Multiphysics. A biological tissue model irradiat...
