1. An anechoic chamber for testing a device under test over-the-air, the anechoic chamber comprising at least one reflecting surface being coupled to a control circuit and being configured to variably manipulate in a defined manner at least one reflection process of at least one electromagnetic wave usable for testing the device under test, wherein a variable manipulation of the reflection process is caused by at least one property of the at least one reflecting surface being variably controlled in-field by a control signal of the control circuit, and wherein at least a direction of the at least one electromagnetic wave is manipulatable based on the variable manipulation of the reflection process.
