It is interesting to note Tesla's patent U.S. Patent 1,329,559 - Valvular Conduit as patent 107 of a total of 111 published US patents, It was one of his last.
I do not believe it to be a stretch of the imagination to assume that an electrical equivalent could have been or was considered as he was versed in both arts, and made / relied on parallels between the two disciplines.
In the beginning of this patent, Tesla clearly states:
Here he state its use for effective control of impulses and its application is obviously to suppress a reversal of flow.
Common circuit theory (in simple form) implies that current remains constant throughout the series impedances. That a change in one part of the circuit simultaneously affects all other parts of the circuit. Within a Tank or (LC) circuit, we have an oscillation of current which inherently implies a reversal of energies.
Imagine a quarter wave resonator (Tesla style secondary). Imagine a current impulse is supplied at the base, the wave travels up to the top-load where it is stored as potential. Instead of letting it reverse direction, let it discharge into the base of a second quarter wave resonator, where it will travel up to its capacitance to be stored as potential, then rather than reverse, it heads to the third then the fourth. Now you have caused the impulse to travel in one direction around 4 quarter wave resonators constituting 360 electrical degrees. At the end of the 4th resonator, the energy is of the correct quality and phase to be re-injected back into the base of the first quarter wave resonator. Here we have a "ring circuit delay line". There are no current reversals, however it does have a resonance, but one that behaves differently from your standard single layer solenoid.
Instrumental to this occurrence is a mechanism to disallow current reversals. You would need some sort of an electrical "Valvular Conduit" to ensure propagation in a single direction. This can be done with a device like the director or...
You could use quarter wave cancellation, a technique used it optics, and microwave circuits. A fantastic paper describing this embodiment is by FJ Tischer - 1957 "Resonance Properties of Ring circuits". Here the 4 quarter wavelength resonators are referred to as 1 wavelength long ring circuit. Knowing that excitation at any tangent would cause a wave propagation in two directions, a second excitation point is introduced 1/4 of the physical wavelength away from the initial impulse. This cancels all waves traveling in one direction, and doubles waves traveling in the other. The result is a circular delay line, which operates off of impulses which propagate in one direction only! This is very very cool, cannot stress this enough. However the application of this as of right now is beyond the scope of most amateurs. This requires one to translate the mechanics of microwave technology, into lumped element theory (which is in reality an unnecessary and complicated approach), in order to deal with more reasonable frequencies. I would ignore this approach for building, but keep it in the back of your mind, it really is incredible (that is unless you understand full well the implications, and the necessary requirements, then by all means...BUILD!). Quarter wave cancellation....

This is a fantastic link, which describes power in a much more "correct" form for what many here are trying to accomplish, and this particular page deals with quarter wave resonators.
Optical Coating Design
This link describes quarter wavelength coatings for optics, resulting in wave wave superposition or cancellation. These are generally known as anti reflective lenses. This DEFINITELY applies to this technology.

In the beginning of this patent, Tesla clearly states:
"In most of the machinery universally employed for the development, transmission and transformation of mechanical energy, fluid impulses are made to pass, more or less freely, through suitable channels or conduits in one direction while their return is effectively checked or entirely prevented."
