Title: Method for analyzing electromagnetic wave
Inventor: IRIYAMA EIJI
IPC: G06F19/00
Filed: 1994-08-31
Abstract: PURPOSE: To make it possible to shorten the computing time of the analysis of an electromagnetic wave by obtaining the first boundary, which is formed by projecting the image of an obstacle on a virtual plane when an electromagnetic-wave generating source is made to be the light source, and providing the second boundary, which is formed by projecting the image of the obstacle on the virtual plane with respect to the light sources that are in parallel with the planes to become the side surfaces of the obstacle regarding the electromagnetic-wave generating source. CONSTITUTION: A boundary 5 is formed by projecting the image of an obstacle 1 when an electromagnetic-wave generating source is made to be a light source 3. A boundary 6 is formed by projecting the image of the obstacle 3 on light sources 3a-3d in parallel with faces, which are to become side surfaces 1a-1d, with respect to the generating source. These boudaries are obtained beforehand. A region 7 at the outside of the boundary 5 is made to be the region, where only the direct wave arrives. A region 8, which is surrounded by the boundary 5 and the boundary 6, is made to be the region, where only one-time diffracted light wave arrives. A region 9, which is surrounded with the boundary 6, is made to be the region, where only twice diffracted wave arrives. The characteristic waves arriving from the generating source are determined in this way.  When the strength of the electromagnetic wave at the arbitrary point in a virtual plane 4 is obtained, the computing time can be shortened by computing only the characteristic waves for every region.

Abstract: PROBLEM TO BE SOLVED: To simply measure an angle and to accurately measure an effective flow velocity by measuring a flow velocity when a flow velocity component is increased and a flow velocity when the component is decreased, and calculating an angle formed between a direction of a mean flow velocity of a fluid based on a plurality of specific formulae and a direction of a channel axis. SOLUTION: A plurality of transducers 1, 2 are oppositely disposed at a predetermined interval on an L line obliquely crossing in a fluid channel, and flow velocity of a fluid is measured. A flow velocity V1 when a flow velocity component is increased and a flow velocity V2 when the component is decreased are measured while measuring a flow velocity V directly measured on a locus L line where an ultrasonic wave is propagated between the transducers 1 and 2. Then, an angle α formed between a direction of the mean flow velocity of the fluid and a direction of a channel axis is calculated based on formulae I and II, and further a channel component V⊥ of the direction of the axis is calculated by using the angle α. When a flow rate is calculated based on this effective flow velocity V⊥, a flow rate measuring accuracy can be improved.
