Abstract: Example embodiments relate to a multiple inputs and multiple outputs (MIMO) analyzer for an accurate control of electromagnetic fields inside a multimode resonant chamber with two or more cavities coupled in an accurate way through a slotted piece with slots or waveguide. The MIMO analyzer may include broadband antennas, different types of lenses, and different stirrers, which may be both metallic and non-metallic. These elements, together with some processes such as precise location of under-test elements out of the lower cavity allow for controlling the electromagnetic fields on its interior. This control permits the emulation of the behavior of wireless communication terminals under different fading scenarios, both indoors and outdoors. Some of the features and procedures of the MIMO analyser may be used in industrial microwave heating processes for drying and curing of materials, also known as microwave ovens, allowing a greater efficiency and homogenization in the processes.

Abstract: The present invention allows for an accurate control of the electromagnetic fields inside a multimode resonant chamber with two or more cavities coupled in an accurate way through a metallic plate with slots or waveguide. The multiple inputs and multiple outputs analyzer (MIMO Analyzer) features several elements such as: broadband antennas, metallic slotted plate, different types of lenses and different stirrers, both metallic and non-metallic. These elements, together with some procedures such as precise location of under-test elements out of the lower cavity allow for controlling the electromagnetic fields on its interior. This control permits the emulation of the behaviour of wireless communication terminals under different fading scenarios, both indoors and outdoors.
