Abstract
A method and system for selectively varying the performance of a test chamber are disclosed. According to one aspect, the performance is affected by a variable absorbing structure of the test chamber. The absorbing structure enables selective exposure of absorbing material to achieve a specific performance.
Claims20
A method for affecting performance of a reverberation chamber, the method comprising:
- positioning a variable absorbing structure within the reverberation chamber at a predetermined position and orientation;
- and
- adjusting absorption of the variable absorbing structure to selectively affect an electromagnetic field distribution in the reverberation chamber and to achieve a repeatable electromagnetic field distribution.
A test chamber, comprising:
- an enclosed housing with at least one at least partially reflective interior wall;
- and
- a variable absorbing structure having absorbing material, the absorbing structure configured to selectively expose the absorbing material to achieve a repeatable specific performance.
A variable electromagnetic absorber for use in a reverberation chamber, the variable electromagnetic absorber comprising:
- an absorbing material at least partially enclosable by reflective material;
- and
- a moveable portion of reflective material configured to selectively and repeatably vary exposure of the absorber material to achieve a repeatable electromagnetic field distribution when the variable electromagnetic absorber is placed in the reverberation chamber.
