Major weather facilities around the world recognize microwave atmospheric sounding is the key to developing technology for forthcoming weather and climate missions. The mission for Hyperspectral Microwave Atmospheric Sounder (HyMAS) Emulator is to produce a model for demonstrating the hyperspectral techniques that retrieve data near 118 and 183 GHz through a 52 channel Intermediate Frequency pr...

The detection of breast cancer in its early stage is a developing research field that can rescue the women affected by cancerous tissues. A modest and skilful approach in microwave imaging (MWI) for data inversion is proposed. MWI in medicinal applications has been famous in last two decades and presently it is using for the detection of breast cancer. Medical imaging by microwave technology ha...

In this paper some novel types of microwave bandpass filters using defected ground structures are investigated. In the microstrip technology the use of defected ground structures (DGS) allows designs of filters with tight couplings, without the necessity of using very narrow coupling gaps. In multilayer filters DGS can be used as coupling elements between resonators, allowing very compact filte...

Studies on methods for fixing foods (with a slight loss of bioactive compounds) and obtaining attractive products are important with respect to current technology. The drying process allows for a product with highly bioactive properties. Drying of Physalis fruit was carried out in a conventional manner, and in a microwave under reduced pressure at 120 W and 480 W. After drying, the fruits were ...

This study investigated the pulping process of cooking rice straw in tris(2-hydroxyethyl) ammonium acetate ionic liquid under microwave irradiation. The optimal processing conditions were determined via othogonal experimentation based on analyses of the effects of the main factors, namely the mass ratio of ionic liquid to rice straw, cooking time, and microwave power, on the cooking of pulp. Th...

Insects and pests constitute a major threat to food supplies all over the world. Some estimates put the loss of food grains because of infestation to about 40% of the world production. Contemporary disinfestation methods are chemical fumigation, ionizing radiation, controlled atmosphere, conventional hot air treatment, and dielectric heating, that is, radio frequency and microwave energy, and s...

M. Stachowicz, J. Mażulis, K. Granat, A. Janus, Wroclaw University of Technology,Department of Foundry Engineering and Automation, Wrocław, Poland The paper presents the results of applying microwaves to support the drying, redrying and hardening process of molding and core sands made of different types of matrix. In the tests of the microwave heating process a slot line measuring stand was use...

High-repetition-rate optical frequency combs can act as broadband photonic mixers and downconvert a microwave signal to an intermediate frequency (IF) band so that it becomes accessible with high-speed electronics. In this Letter, we show that with line-by-line pulse shaping and dispersive propagation, the photonic mixer can simultaneously perform programmable multitap complex-coefficient-filte...

The last few years have seen a large development of mm technology and ultra-sensitive detectors devoted to microwave astronomy and astrophysics. The possibility to deal with large numbers of these detectors assembled into multi–pixel imaging systems has greatly improved the performance of microwave observations, even from ground–based stations, especially combining the power of multi–band detec...

In this paper, we investigate the high frequency performance of Co90Zr10/SiO2/Co90Zr10 trilayers. It is demonstrated that the in-plane isotropic microwave performance is theoretically derived from the solution of the Landau-Lifshitz-Gilbert equation and experimentally achieved in that sandwich structured film. The valuable isotropic behavior comes from the superposition of two uncouple ferromag...
