How does Skin-Effect Corrent Tracing technology affect the efficiency of high-frequency circuit design?

The impact of Skin-Effect Corrent Tracing (SECT) technology in high-frequency circuit design is mainly reflected in the effect of skin effect on circuit efficiency. The following is a specific analysis:
Definition of skin effect: When there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is mainly concentrated in the "skin" part of the conductor, that is, the thin layer on the surface of the conductor. This phenomenon of current concentration on the surface of the conductor is called skin effect.
Influence on resistance: Due to the skin effect, the effective cross-sectional area of ​​high-frequency current in the conductor is reduced, resulting in an increase in the resistance of the conductor. The increase in resistance will also increase the power loss of the conductor, thereby reducing the efficiency of the circuit.
Influence on high-frequency circuit design:
Increase in resistance: In high-frequency circuits, the increase in resistance caused by the skin effect will increase the energy loss in the circuit, thereby reducing the efficiency of the circuit.
Wire selection: In order to reduce the impact of the skin effect, hollow wires or tubular wires are usually selected instead of solid wires in high-frequency circuit design, so that more conductor surfaces can be used to carry current, thereby reducing resistance and loss.
Material selection: Selecting materials with high conductivity (such as copper, silver, etc.) can also reduce the impact of the skin effect, because high conductivity materials can transmit current more efficiently, reducing resistance and loss.
Frequency considerations: When designing high-frequency circuits, it is necessary to consider the relationship between skin effect and frequency. The higher the frequency, the more significant the skin effect, so it is necessary to select the appropriate frequency and wire material according to the specific application scenario.
Application of SECT technology: SECT technology is based on the principle of skin effect and improves the efficiency of the circuit by optimizing the distribution of current in the conductor. In high-frequency circuits, SECT technology can be used in heating and insulation of metal pipes, electromagnetic shielding, etc. to improve the performance and efficiency of the circuit.
In summary, Skin-Effect Corrent Tracing (SECT) technology optimizes the distribution of current in high-frequency circuit design by utilizing the principle of skin effect, thereby reducing resistance and loss and improving the efficiency of the circuit. In practical applications, it is necessary to select appropriate wire materials, frequencies and circuit design solutions according to specific application scenarios to give full play to the advantages of SECT technology.
