Electromagnetic Transmission

In summary, electromagnetic transmission is the process of sending or receiving information or energy through the use of electromagnetic waves. These waves can travel through a vacuum or medium and do not require a physical medium, making it different from other forms of communication. Some common uses include radio and television broadcasting, cellular and satellite communication, and medical imaging. While there have been concerns about potential health risks, research has not found any conclusive evidence of harmful effects on human health.

Figure below shows a load made up of a 50 W resistance, a 15 nH inductance and a 22 pF
capacitance connected in series. The load is terminated to a two-wire transmission line with
characteristics impedance of 50 W.



(i) Determine the load reflection coefficient at an operating frequency of 900 MHz, from
the Smith chart.

(ii) Calculate the standing wave ratio on the transmission line.

(iii) Determine the input impedance at 0.15 l away from the load using the Smith chart,
where l is the wavelength at the operating frequency.

Help me answer this question :cool:

Related to Electromagnetic Transmission

What is electromagnetic transmission?

Electromagnetic transmission is the process of sending or receiving information or energy through the use of electromagnetic waves. This includes technologies such as radio, television, and wireless communication.

How do electromagnetic waves travel?

Electromagnetic waves travel through a vacuum or through a medium, such as air or water, at the speed of light. They are created by the movement of electrically charged particles and can travel through different materials.

What is the difference between electromagnetic transmission and other forms of communication?

Electromagnetic transmission differs from other forms of communication, such as sound transmission, because it does not require a physical medium to travel through. Instead, it uses electromagnetic waves to transmit information or energy.

What are some common uses of electromagnetic transmission?

Electromagnetic transmission is used in a variety of ways, including radio and television broadcasting, cellular and satellite communication, radar and sonar systems, and medical imaging technologies like X-rays and MRI scans.

What are the potential health risks associated with electromagnetic transmission?

There have been concerns about potential health risks associated with exposure to electromagnetic waves, particularly from sources like cell phones and Wi-Fi. However, extensive research has not found any conclusive evidence of harmful effects on human health from electromagnetic transmission.
