Low-Frequency Model for Radio-Frequency Absorbers
A simple model is developed to characterize the behavior of radio-frequency absorbers at low frequency. The absorber is represented by a flat, homogeneous, isotropic slab of lossy material, with effective constitutive parameters. These parameters are determined by a fit to measured data. Excellent fits are obtained in the two applications considered. The model is intended for use in the charact...
متن کاملLow Frequency Radio Observations Of W51 Complex
W51 is a giant radio complex lying along the tangent to the Saggitarius arm at a distance of about 7kpc from Sun, with an extension of about 1◦ in the sky. It is divided into three components A,B,C where W51A and W51B are regions consisting of many compact HII sources.We have made continuum radio observations of these HII regions of W51 complex at 240,610,1060,1400 MHz frequencies using GMRT. T...
متن کاملLOFAR, a new low frequency radio telescope
LOFAR, the Low Frequency Array, is a large radio telescope consisting of approximately 100 soccer-field sized antenna stations spread over a region of 400 km in diameter. It will operate at frequencies from ∼ 10 to 240 MHz, with a resolution at 240 MHz of better than an arcsecond. Its superb sensitivity will allow for studies of a broad range of astrophysical topics, including reionisation, tra...
متن کاملReceivers for Low-Frequency Radio Astronomy
The next generation of large telescopes for low-frequency radio astronomy will consist of tens of thousands of broadband antennas, each individually instrumented with receivers having large tuning range and instantaneous bandwidth. Because the number of receivers is very large, their cost must be minimized; however the receivers must be also be able to cope with the severe interference associat...
متن کاملRadio Frequency-micro Electromechanical System Switch with High Speed and Low Actuated Voltage
This paper presents a novel RF MEMS (Micro Electromechanical System) fixed-fixed switch for very fast switching. Using the obtained equations, the switching time depends on the stiffness and effective mass of the switch beam so that the switching time will be decreased by higher stiffness (spring constant) and lower effective mass. In new design, the suspension bridge is a three-layer beam so t...
