Experimental simulation of satellite observations of 100 kHz radio waves from relativistic electron beams above thunderclouds [PDF]
Atmospheric Chemistry and Physics, 2011 Relativistic electron beams above thunderclouds emit 100 kHz radio waves which illuminate the Earth's atmosphere and near-Earth space. This contribution aims to clarify the physical processes which are relevant for the spatial spreading of the radio ...

Propagation of Electromagnetic Wave into an Illuminated Polysilicon PV Cell
International Journal of Antennas and Propagation, 2020 The increasing cohabitation between telecommunication antennas generating electromagnetic waves and solar panels poses the problem of interaction between these radio waves and solar cells. In order to study the effect of radio waves on the performance of

ENHANCEMENT OF BANDWIDTH AND BEAM FORMING ANTENNA ARRAYS IN 5G CELLULAR COMMUNICATION NETWORKS
ICTACT Journal on Communication Technology, 2022 In general, an antenna is an interface that transmits signal data and receives incoming signal data. The radio waves received through this interface help to do the necessary things for the transmitter and receiver circuit systems used there. Also a radio
