Is there a relatively simple and efficient way of creating resonance within a broad range of the RF spectrum, such that the effect of existing RF fields are enlarged?
Almost by definition, resonance means a sharp peak or trough in response over a narrow frequency range.Is there a relatively simple and efficient way of creating resonance within a broad range of the RF spectrum
Sounds like incoherent rambling, unless I'm missing something.Theoretical speaking, you have a point when it comes to principles behind electronics.
Notice however the effect on other frequencies in the RF spectrum then emitting distorted RF signals with large near field effect, e.g. RF signals, generated by electronic circuits, consisting of convolutions of sinus wave and 'saw-tooth' waves at higher frequencies (multiple of frequency/wavelength).
What are you talking about? Electromagnetic energy is the same everywhere but you can modify it's local energy distribution by the introduction of a non-linear travel path for that energy for mixing/heterodyne to create new frequencies and/or 'beating' a near frequency for the superposition of signals creating a detectable envelope. Simple harmonic oscillator type resonance effects tend to store energy (Q) that normally would be dissipated in the background as undetectable heat quickly making detection possible above the noise level but all that is common knowledge.I am saying radio fields aren't electronic circuits.
The phenomenon has been observed across a wide frequency range. Resonance effects observable in multiples of a particular frequency and with different effect proportional to the distance from the center frequency of the emitted field. A consequence of a less precise convolution of two signals.
However, there are more advanced examples, generating more uniform observable phenomena.

Yes, electrically it's like ringing a bell with a quick rap from a solid rod or the drop of a piano hammer on the tight string of the sounding board. Instead of mechanical motion and moving mass you have the electrical energy entering the circuit being stored and released in time back and forth as electric and magnetic fields in the reactive components and/or parasitic impedance of the components.I was looking for answers elaborating on this thread: http://forum.allaboutcircuits.com/threads/resonance.104084/
"Suddenly starting or stopping a sinusoidal signal generates a wide spectrum. Even though the frequency of that sinusoid is far removed from the resonance of the LC circuit, some of the sideband energy caused by a high dv/dt will cause the LC tuned circuit to ring a little bit, especially if it has a high Q. (Hams call this key clicks).
The circuit would be excited by any high dv/dt signal, regardless if it is a sharply keyed sinusoidal signal or something else"
Read and understand this book to find out.Ok, and besides the poetry. Signal generators, RLC circuits, amplifiers and antennas - what is the point of building those in vain or of low quality, when others have already done so. Where are the adjustable, flexible designs, schema and simple affordable components lists and the textbook to rule them all.
