Electromagnetic waves are a radio, light, X-rays and gamma rays. However, traditionally electromagnetic waves considered in scientific and in academic literature in different positions. Radio waves are always considered as a waves, while light is represen... see more

In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these bands, with the measurement for each of them of the el... see more

Since 1996, the electric field strength of the two broadcasting stations MCO (f=216 kHz, southeast France) andCZE (f=270 kHz, Czech Republic) has been sampled every ten minutes by a receiver (AS) located in centralItaly. Here, we review the results obtain... see more

Due to the prominent topography of Mt. Etna, the use of satellite geodetic techniques may significantly suffer from atmospheric heterogeneities. This problem mainly affects the DInSAR technique. To overcome these drawbacks the present study attempts to ma... see more

The remarkable technology for seamless integration of wireless and optical networks is radio frequency signals over Free Space Optics (FSO). This research study and simulation examine the design and evaluation performance of Radio Frequency over FSO (RF-F... see more

Standoff detection of concealed threat, using millimeter wave radiometer, is being experimented worldwide for enhancing the frame rate and detection probability, as an alternative to personnel frisking, for enhancing passenger service rate and avoiding ex... see more

In telecommunication channel modelling the wavelength is small compared to the physical features of interest, therefore deterministic ray tracing techniques provide solutions that are more efficient, faster and still within time constraints than current n... see more

Given the inherent need to have technological tools to reduce the number of incidents caused by the operation of heavy machinery, this document briefly describes the design of a prototype Accident Prevention System for industrial vehicles using Radio Fre... see more

There is a huge body of evidence in the literature that exposure to radio frequency (RF) has been linked to a variety of adverse health outcomes that may have significant health problems for user of mobile phone. Credible scientific evidences are there th... see more
