Radio Friendly Waves
In a place where no television can be found, no telephone, no internet, they rely for outside communication, news, and entertainment through transistor radio. As a child, growing up in a small village with only the radio to entertain ourselves, we get used to this type of broadcasting. In a distance, I can see a large tower, according to my grandfather, was where the voices I heard in our radio come from.
I still can’t believe that those songs, news, and advertisements are coming from the tower. I asked him again, how come I cannot see anyone up there? That is because we cannot see wavelengths. That was the answer I got. The word lingers around my head until the day I finally met the word. It turned out to be an invisible force that’s transmitted from source to destination.
I finally learned about waveguide transitions as an element to which this invisible force utilized to broadcast signals. I was hooked to the idea of waveguides, wavelengths, transmitters and receivers. In the course of my education, I studied every aspect of electromagnetic waves up to double ridge waveguide along with the physical components of that propagates signals to the community until today.
