Abstract
A method for measuring the performance of a reconfigurable intelligent surface is provided. Said method comprises the steps of transmitting (100) a transmit signal to the reconfigurable intelligent surface, receiving (101) the corresponding refection from the reconfigurable intelligent surface as a receive signal, and comparing (102) the transmit signal and the receive signal to determine or derive phase and/or amplitude changes imposed by the reconfigurable intelligent surface.
Claims20
A method for measuring one or more characteristics of a reconfigurable intelligent surface with the aid of a measurement device, the method comprising the steps of:
- transmitting a transmit signal to the reconfigurable intelligent surface,
- receiving the corresponding reflection from the reconfigurable intelligent surface as a receive signal,
- comparing the transmit signal and the receive signal to determine or derive a phase change, an amplitude change, or a combination thereof imposed by the reconfigurable intelligent surface, and
- assisting, when manually moving the measurement device, by an optical motion tracker that provides corresponding positioning information of the measurement device.
A measurement device for measuring one or more characteristics of a reconfigurable intelligent surface, the measurement device being configured to support, to perform, or a combination thereof:
- transmitting a transmit signal to the reconfigurable intelligent surface,
- receiving the corresponding reflection from the reconfigurable intelligent surface as a receive signal, and
- comparing the transmit signal and the receive signal to determine or derive a phase change, an amplitude change, or a combination thereof imposed by the reconfigurable intelligent surface, wherein manually moving the measurement device is assisted by an optical motion tracker that provides corresponding positioning information of the measurement device.
A measurement system for measuring one or more characteristics of a reconfigurable intelligent surface, the measurement system comprising:
- the reconfigurable intelligent surface, an optical motion tracker, and
- a measurement device being configured to:
- transmit a transmit signal to the reconfigurable intelligent surface,
- receive the corresponding reflection from the reconfigurable intelligent surface as a receive signal, and
- compare the transmit signal and the receive signal to determine or derive a phase change, an amplitude change, or a combination thereof imposed by the reconfigurable intelligent surface,
- wherein manually moving the measurement device is assisted by the optical motion tracker that provides corresponding positioning information of the measurement device.
