Microwave-induced thermoacoustic tomography was explored to image biological tissues. Short microwave pulses irradiated tissues to generate acoustic waves by thermoelastic expansion. The microwave-induced thermoacoustic waves were detected with a focused ultrasonic transducer to obtain two-dimensional tomographic images of biological tissues. The dependence of the axial and the lateral resoluti...

This paper mainly presents a briefly review for recent progress in MEMS-based transmission lines for use in microwave and millimeterwave range. MEMS-based transmission lines including different transmission line structure such as membranesupported microstrip line microstrip line, coplanar microshield transmission line, LIGA micromachined planar transmission line, micromachined waveguides and co...

Microwave heating is applied for processing different silicon raw materials, based on the size-, shapeand composition-dependent absorption of radiation of 2.45 and 916 MHz frequency by silicon. In model experiments directed towards the improvement of melting technology, Si-fines and chunks of bulk Silicon from Electronic Grade (EG)and Solar Grade (SG)-silicon production are used as raw material...

BACKGROUND Carbon nanotube (CNT) characteristics, besides the processing conditions, can change significantly the microwave absorption behavior of CNT/polymer composites. In this study, we investigated the influence of three commercial multi-walled CNT materials with various diameters and length-to-diameter aspect ratios on the X-band microwave absorption of epoxy nanocomposites with CNT conten...

Microwave energy has been widely used in several domestic, industrial, and medical applications such as food sterilization, organic/inorganic syntheses, polymerization, dehydration, analyses and extraction, and biological destruction. This paper summarizes the potential applications of microwave energy as remedial alternatives for various types of wastes and diverse contamination of soils, slud...

Since the great experiments were carried out by Dr. Percy Spencer in 1946, microwave heating has been used widely in food industry, medicine, chemical engineering and so on [1][2][3][4][5], for processing many materials ranging from foodstuffs [1][6][7][8] to tobaccos [9][10][11], from wood [12][13][14] to ceramics [15][16][17][18], and from biological objects [19][20] to chemical reactions [21...
