This study experimentally clarifies that the causes by which the radio control clock sometimes fails to receive the standard time signal in the indoors are in the following two factors: (1) the shielding by the conductive materials (used for column, pillar, floor and so on) existing close to the radio control clock. (2) The missing of tuning and the change of Q of the antenna due to the closely existing...
The following topics are dealt with: lightning, ESD and EMP; EMC in communications; EMC test and measurement; EMC control; antenna and propagation; modeling and calculation and electromagnetic biological effect.
In this paper, the simulation and measurement is done in order to research the transverse attenuation characteristics of the radio disturbance form the electrified railway in the shortwave band. Comparison is made between the simulation results and measurement results. It is concluded that the radio noises produced by the electric railway in the shortwave band should not influence the field transmitted...
