| 20100163837 | GUNN DIODE - A Gunn diode includes an active layer having a top and a bottom, a first contact layer disposed adjacent to the top of the active layer, a second contact layer disposed adjacent to the bottom of the active layer, wherein the first and second contact layers are more heavily doped than the active layer, and at least one outer contact layer disposed at an outer region of at least one of the first and second contact layers, the at least one outer contact layer being more heavily doped than the first and second contact layers, wherein the first and second contact layers, the active layer, and the at least one outer contact layer include a base material that is the same. | 07-01-2010 |
| 20100148804 | DEVICE AND METHOD FOR DETERMINING AT LEAST ONE PARAMETER OF A MEDIUM - The invention relates to a device for determining at least one parameter of at least one medium, said medium being introducible into at least one measuring path. An electric and/or electromagnetic field can be partially coupled into or out of the medium by passing at least one electric and/or electromagnetic signal into the measuring path. The measuring path comprises at least one line arrangement having at least two elementary cells arranged along the measuring path, said elementary cells comprising at least one electric path from at least one input to at least one output and comprising at least one respective capacitative element. The electrical properties of the capacitative element can by be modified by the medium. The electric and/or the electromagnetic signal can be applied to the input of a first elementary cell and the output of the first elementary cell can be connected to the input of a second elementary cell. The capacitative element of the respective elementary cell is arranged in the electric path of the first and second elementary cell. At least one inductive element connects the first elementary cell and the second elementary cell to a ground. The invention also relates to a method for determining a parameter of a medium. | 06-17-2010 |
