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.

  • Patent number: 8729440
    Abstract: A radio frequency heater is disclosed including a vessel for containing material to be heated and a radio frequency radiating surface. The vessel has a wall defining a reservoir. The radio frequency radiating surface at least partially surrounds the reservoir. The radiating surface includes two or more circumferentially spaced petals that are electrically isolated from other petals. The petals are positioned to irradiate at least a portion of the reservoir, and are adapted for connection to a source of radio frequency alternating current. A generally conical tank or tank segment having a conically wound radio frequency applicator is also contemplated. Also, a method of heating an oil-water process stream is disclosed. In this method a radio frequency heater and an oil-water process stream are provided. The process stream is irradiated with the heater, thus heating the water phase of the process stream.

  • Publication number: 20140117008
    Abstract: A pressure vessel for receiving samples to be heated is provided, the pressure vessel has a closable reaction chamber as a pressure chamber for initiating and/or promoting chemical and/or physical pressure reactions, and the pressure vessel has a microwave-permeable region, by way of which microwaves can be coupled into the reaction chamber. A hollow light guide pipe extends from the microwave-permeable region towards an infrared sensor, which is arranged outside the pressure chamber, and by way of which the infrared radiation emitted by the heated samples in the reaction chamber is guided during a pressure reaction to the infrared sensor. In the microwave-permeable region, an infrared-permeable pressure receiving part is provided, between the reaction chamber and the light guide pipe and lies against the reaction chamber, in order to support the light guide pipe in the microwave-permeable region.
