Abstract: A lighting device with a plurality of light-emitting elements such as light-emitting diodes disposed in an in-line configuration at regular interval on a base plate; and a plurality of reflectors attached to the base plate, the plurality of reflectors being so formed as to cover each of the light-emitting diodes with mixed reflecting surfaces structured by reflecting surfaces which are planar except their lower portions, the planar reflecting surfaces being perpendicular to in-line direction of the light-emitting elements such as diodes, and other side surfaces which are able to mix reflected lights from the light-emitting elements; therefore, the present invention provides economical lighting devices which can illuminate relatively wide area nearly evenly by effectively mixing the lights from the light-emitting elements such as light-emitting diodes, and further which can be used like conventional electric lamps and fluorescent lights.

Abstract: An electromagnetic field intensity calculation apparatus calculates a virtual current vector from a voltage vector and a mutual immittance matrix of an object including a wave source where a wave source power is applied. The voltage vector and the mutual immittance use a wave voltage of the wave source as a unit voltage. The apparatus also calculates an input impedance of the wave source based on a virtual wave source current of the virtual current vector and a unit voltage of the wave source, and calculates the wave source voltage based on the input impedance and the wave source power. The apparatus further calculates a current vector based on the wave source voltage calculated and the virtual current vector, and calculates an electromagnetic field intensity around the wave source which is determined based on the current vector.
