SEMICONDUCTOR ELEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18156539 titled 'SEMICONDUCTOR ELEMENT

Simplified Explanation

The patent application describes a semiconductor element that includes an antenna array with multiple antennas, each having a semiconductor layer that interacts with terahertz waves. The antennas are synchronized using a coupling line at the terahertz wave frequency.

• The antenna array consists of multiple antennas with semiconductor layers that have electromagnetic wave gain or carrier nonlinearity with respect to terahertz waves.
• A coupling line is used to synchronize adjacent antennas in the array at the terahertz wave frequency.
• The coupling line includes multiple first regions connected to the adjacent antennas and a second region between them.
• The second region has a different impedance compared to the first regions and has a higher loss at frequencies other than the resonance frequency of the antenna array.

Potential applications of this technology:

• Terahertz communication systems: The semiconductor element can be used in terahertz communication systems to enhance the gain and nonlinearity of the antennas, improving the overall performance of the system.
• Terahertz imaging: The semiconductor element can be utilized in terahertz imaging devices to enhance the sensitivity and resolution of the antennas, allowing for more accurate and detailed imaging.

Problems solved by this technology:

• Improved synchronization: The coupling line ensures that adjacent antennas in the array are synchronized, which is crucial for the proper functioning of the semiconductor element.
• Enhanced performance: The use of semiconductor layers with electromagnetic wave gain or carrier nonlinearity improves the performance of the antennas, leading to better signal reception and transmission.

Benefits of this technology:

• Increased efficiency: The semiconductor element improves the efficiency of terahertz communication systems and terahertz imaging devices by enhancing the gain, nonlinearity, sensitivity, and resolution of the antennas.
• Improved signal quality: The synchronization of the antennas and the use of semiconductor layers with gain or nonlinearity result in better signal quality, reducing noise and interference.
