| Antenna Briefs #5 - Electric Fields, Magnetic Fields, and EM Waves This video focuses on understanding electric, magnetic, and electromagnetic fields produced by antennas. This knowledge will be essential in future antenna topics, but we also provide some key engineering results here. For example: How do we find the field strength in volts/meter produced by an antenna and how do we map that to the voltage that a receiving antenna produces? How can we build transmitters that obey regulatory rules? A brief preview of the next episode is also provided, where we ask the questions: what is a B field (spoiler: it's really just an E field in another relativistic frame of reference), and how do we calculate and simulate far-field patterns from antennas... https://youtu.be/6C-IETDAY1s |
