Abstract: An electromagnetic wave visualization device includes an image acquisition unit that captures an image of a target device, a measurement unit that measures an electromagnetic wave intensity of the target device, a controller that generates a composite image in which a measurement result of the electromagnetic wave intensity measured by the measurement unit is superimposed on the captured image of the target device acquired by the image acquisition unit, an output unit that outputs the composite image, and a distance measuring unit that measures a distance from the measurement unit to the target device. The controller determines, whether or not the distance measured by the distance measuring unit is within a predetermined distance at which the electromagnetic wave intensity in the frequency bandwidth is measurable, generates an alert in a case where the distance is not within the predetermined distance, and causes the output unit to output the alert.

Abstract: A radio wave measurement device includes a housing having a metallic layer, and a horizontal polarization antenna and a vertical polarization antenna that are both disposed on one face of the housing. The horizontal polarization antenna receives horizontally polarized waves, whereas the vertical polarization antenna receives vertically polarized waves. The radio wave measurement device further includes a switching unit connected to both the horizontal polarization antenna and the vertical polarization antenna, and an output unit connected to the switching unit. The switching unit includes a connection part connected to the output unit and a resistance part connected to a resistor. The switching unit switches between the antennas such that only one of the horizontal polarization antenna and the vertical polarization antenna is connected to the connection part, and the other antenna is connected to the resistor.
