Abstract: An information processing apparatus performs electromagnetic field analysis over a plurality of stages. The information processing apparatus includes a hardware processor connected to a memory. The hardware processor sequentially selects an analysis target and determines one or more analysis regions in the analysis target. The one or more analysis regions are determined on the basis of a parameter relative to mutual influence between structures included in the analysis target. The hardware processor performs electromagnetic field analysis on the one or more analysis regions. The structures include a first structure and a second structure. At least one of the one or more analysis regions includes an entirety of the first structure and part of the second structure.

Abstract: An antenna device is mounted on a vehicle and performs vehicle-to-vehicle and road-to-vehicle communications using a plurality of communicators including antennas. The antenna device includes one or more hardware processors coupled to one or more memories, and configured to function as, communication control units, a vehicle state detection unit, and operation control units. Communication control units are each provided in one of the plurality of communicators and control transmission/reception operations of the antennas connected to the communicators. A vehicle state detection unit detects a state of the vehicle and operation states of the communication control units. Operation control units are each provided in one of the plurality of communicators and control the operation states of the communication control units according to the state of the vehicle detected by the vehicle state detection unit and the operation states of the communication control units, for each of the plurality of communicators.
