Abstract :
Recently, energy-conservation equipment such as an LED lamp becomes used gradually. However, such equipment has possibilities to radiate unintentional electromagnetic noises. The unintended noises often interfere in wireless communications such as multimedia broadcastings or digital television broadcastings. Especially, the emission of LED lamps has wide frequency range up several hundred megahertz. In this report, the electromagnetic-field attenuations of some kind of buildings in very-high frequency band are numerically analyzed by using the finite-integration (FI) method.
