Is there any possibility of storage of electromagnetic waves ?

Drakkith said:Yes, but not for the purposes of long-term energy storage. The intensity of the wave and the time frame you can keep it 'stored' is small due to unavoidable losses.
Drakkith said:I'm not sure what to say. In any application where we use EM waves we have losses. There is no such thing as a perfect reflector, so any time an EM wave is reflected it loses energy.
Drakkith said:I'm sorry but I cannot understand your question.
Drakkith said:It's not that the losses aren't recoverable. Some of them actually are. It's that if you already have losses, then you're better off just converting the light into a form of energy that can be stored without those losses in the first place. It's MUCH easier and cheaper to convert light into heat, electrical, chemical, or another source of potential energy than to try to store the light directly.

A wave is a 'dynamic' phenomenon. The only way to 'store a wave' is to keep it inside a cavity of some sort with reflective surfaces. Such a cavity would have surfaces with finite resistivity and that would cause power to be dissipated very quickly.nilesh_pat said:Ok Sir. Could be store any of frequency from AM to Satellite - ( 530 kHz to 12 GHz)

Drakkith said:Sure, but only for a fraction of a second. That's how quickly you'll lose all of the energy if you don't convert the energy of the EM wave into something else that's easier to store.

An example: If you lost as little as 1% at each reflection and the radiation were kept in a space between two curved mirrors, separated by 3m (a simple example), in a second, there would be 108 reflections, producing 0.99 to the power of 108. Your calculator will not show you enough zeros to tell you how much of the original energy would be left.
Electromagnetic wave storage refers to the process of storing electromagnetic waves, which are a type of energy that can travel through space in the form of waves. These waves are typically used for communication and can be stored in various forms, such as in the Earth's magnetic field or in electronic devices.
Electromagnetic waves can be stored through various methods, depending on the specific application. Some common methods include using antennas to store radio waves, using magnetic storage media for storing data in electronic devices, and using the Earth's magnetic field for long-term storage of low-frequency waves.
Storing electromagnetic waves allows for efficient and reliable communication, as well as the ability to transmit and receive information over long distances. Additionally, storing electromagnetic waves can also be used for scientific research and exploration, such as studying the Earth's magnetic field or detecting distant objects in space.
While there are no known health risks associated with storing electromagnetic waves, there are some concerns about potential interference with other electronic devices. It is important to properly regulate the storage and use of electromagnetic waves to avoid any potential negative effects.
Researchers are constantly working on improving the storage of electromagnetic waves through advancements in technology, such as developing more efficient antennas and storage devices. Additionally, careful planning and regulation of the use of electromagnetic waves can also help improve storage methods.
