Because of eddy currents in copper that produce losses and attenuation, ac currents in the copper are forced to the outer surface (see skin effect in reference books). This begins to happen below 1 MHz. By 1 THz the skin depth is very thin.priyadarshan said:Sir I have read that each medium has its bandwidth limitations not regarding heat loss... so I was asking in such way that Can copper pass THz signals?...If no than why?

Signal propagation refers to the transmission of a signal through a medium. It is important because it allows information to be communicated from one point to another, enabling technologies such as wireless communication and the internet.
Signal propagation can affect communication in various ways. Factors such as distance, obstacles, and interference can cause signal degradation, resulting in poor signal quality or loss of signal. This can lead to errors in communication or complete failure of transmission.
The characteristics of signal propagation include amplitude, frequency, wavelength, and propagation speed. Amplitude refers to the strength or power of the signal, frequency is the number of cycles per second, wavelength is the distance between two consecutive peaks, and propagation speed is the speed at which the signal travels through the medium.
The medium through which the signal travels can greatly affect signal propagation. Different mediums, such as air, water, or fiber optic cables, have varying properties that can impact the speed, strength, and quality of the signal. For example, signals can travel faster and with less interference through fiber optic cables compared to wireless transmission through air.
Some techniques used to improve signal propagation include using repeaters or amplifiers to boost the signal, using directional antennas to focus the signal in a specific direction, and using coding and modulation techniques to reduce errors and interference. Additionally, using a medium with lower attenuation, such as fiber optic cables, can also improve signal propagation.
