- jjoonathan 8y agoYou can find more information under the term "dielectric resonator." Searching "dielectric resonator modes" yields a high concentration of promising figures. "Ceramic antenna" is a term that will yield information on the applications of this idea to antennas.
- dbcurtis 8y agoYes, that is kind of non-sensical as written. I'm going to guess that by "antenna" they are thinking of "resonant dipole" and by referring to a trombone, they are saying the grape is more of a resonant cavity. But then again, a trombone is not a resonant cavity in the RF sense -- it resonates as a tube closed at one end.
- rdiddly 8y agoI found that annoying, since the resonance of EM waves in an antenna is not only a perfectly fine analogy to sound waves resonating in the trombone, it's literally what's happening in the grape, unless I'm missing something.
