A relatively new method based on measurements by multipoint continuous Doppler sounding is applied to study the occurrence rate, propagation velocities, and directions of spread F structures over Tucumán, Northern Argentina, and Taiwan, both of which were under the crest of the equatorial ionization anomaly in 2014. In addition, spread F is studied globally over the same time period from the S4 scintillation...
Electromagnetic interference in frequencies below the 100 kHz range is an important part of electromagnetic interference in general. Low voltage electrical installations with voltages of 110V or 240V and with frequencies of 50/60Hz are omnipresent. They are present in some industrial environments, some office spaces and in domestic homes. These power lines are linked with electrical instruments, metallic...
In recent years, bringing a reliable communication and transmission in an indoor scenario via wirelessly due to its advantages, which is the elimination of the electric wire as well as a conveyance with a moving object is emerging. Considering that the electromagnetic radiation through a working garment has been drawing particular attention. From the sensor communication system point of view a wide...
Over the past 10 years there have been rapid advances in wireless technologies and an importance of a radio frequency (RF) communication system is expanding day by day due to its advantages. In the meantime, a huge number of researchers are investigating from the various aspects of a such field. Electromagnetic wave propagation in an indoor environment and penetration trough environment medium is...
