Electromagnetic wave oscillator, plasma wave power extractor and electromagnetic wave detector

A plasma wave power extractor, comprising:

• a 2DEG (two-dimensional electron gas) plate configured to form a 2DEG channel;
• a first resistor connected to one side node of the 2DEG plate;
• a second resistor connected to an opposite side node of the 2DEG plate;
• a source disposed between the second resistor and a ground and configured to apply electric power to the 2DEG plate;
• and
• an extractor configured to extract electric power from a drain node between the 2DEG plate and the second resistor when a plasma wave is formed in the 2DEG plate by the source.

An electromagnetic wave detector, comprising:

• a floating plate on which an electromagnetic wave is irradiated to form electric dipoles;
• a 2DEG (two-dimensional electron gas) plate in which a 2DEG channel is formed by the electric dipoles to detect a 2DEG resonance;
• a first resistor connected to one side node of the 2DEG plate;
• a second resistor connected to an opposite side node of the 2DEG plate;
• a source disposed between the second resistor and a ground and configured to apply electric power to the 2DEG plate;
• and
• a dielectric body formed between the 2DEG plate and the floating plate.
