    摘要: A measuring method that includes holding a specimen to be measured on a flat-plate periodic structure, applying a linearly-polarized electromagnetic wave to the flat-plate periodic structure, detecting the electromagnetic wave scattered forward or backward by the flat-plate periodic structure, and measuring characteristics of the specimen on the basis of a phenomenon that a dip waveform appearing in a frequency characteristic of the forward-scattered electromagnetic wave or a peak waveform appearing in a frequency characteristic of the backward-scattered electromagnetic wave is changed with the presence of the specimen. The flat-plate periodic structure is a flat-plate structure in which at least two voids penetrating through the structure in a direction perpendicular to a principal surface thereof are periodically arrayed in at least one direction on the principal surface, and the electromagnetic wave is applied to the principal surface of the flat-plate periodic structure from the direction perpendicular to the principal surface.

    摘要: A wiper apparatus includes: a wiper blade driven by a first motor; and a wiper blade driven by a second motor. The motors are drive-controlled by control microcomputers, respectively. The control microcomputers are connected to each other through a communication line. While exchanging position information of the wiper blades through the communication line, the control microcomputers synchronously drive the motors on the basis of a position relationship between both of the wiper blades. When an abnormality occurs in a communication state of an in-vehicle LAN, a setting state of a wiper switch is grasped through a switch signal line directly connected to the wiper switch, and wipers are prevented from being stopped when such communication abnormality occurs.
