    Mesmerizing, I wasn't aware of this patent... thank you for pointing this out.

    Is it possible for you to post that portion of the patent prior to the phrase "To wit?" Also, could you include "Fig. 3?" I see all the others but I don't see Fig. 3. If it's there I can't see it.

    I also do not see the word "Metamaterial" appear in the body of the patent verbiage. While I can see that Marconi's "Reflector" has some attributes of a Metamaterial you will have show me where this is a patent for Metamaterial. Otherwise this looks like a patent for a Reflector. And, so this brings me to the question: Did Marconi know he was inventing Metamaterials? Or was he thinking that he was inventing a reflector for Radio Waves?

    Please excuse me for being critical of what you say, it's just you have my curiosity up now...

    'Metamaterial' is a modern, coined term. Fig 11, in form and function, on that patent, is described by that term. Therefore Marconi and Franklin did the first metamaterial.

    Go dig out the patent--the number is listed :)

    Whilst Marconi was certainly bright and a serous contributor (as well as better organized), I'd hate to see Tesla left off the list of radio inventors. 'tho Tesla did often act a bit scatterbrained, there is no doubt in my mind that he was one of our rarest geniuses and far above many of that day in contributions.

    Oh i'm sorry...
    Well, let's talk about inventors. Who is it?
    Then God said, "And now we will make human beings; they will be like us and resemble us... " Genesis 1.26
    So I can to assert that all people are inventors, because they "are like their Father". )))
    Now let's look at the "first" inventor and what happened then.
    "Zillah gave birth to Tubal Cain, who made all kinds of tools out of bronze and iron.
    Lamech said to his wives, "Adah and Zillah, listen to me: I have killed a young man because he struck me.
    If seven lives are taken to pay for killing Cain, Seventy-seven will be taken if anyone kils me."
    Genesis 4.22
    It's a familiar story, right?
    After the works of inventors appear, politicians start to threaten each other.
    Without the help of inventors, they would have had only empty fists. )))
    But now they have atomic weapons and no one can guarantee that will not appear such a crazy politic or general like in the film Dr. Strangelove.

    How do the inventors justify their participation in this?
    Let's listen to Dr. Wernher von Braun:
    /In spring 1940, one SS-Standartenfuehrer (SS-colonel) Mueller from Greifswald, a bigger town in the vicinity of Peenemünde, looked me up in my office ... and told me that Reichsfuehrer SS Himmler had sent him with the order to urge me to join the SS. I told him I was so busy with my rocket work that I had no time to spare for any political activity. He then told me, that ... the SS would cost me no time at all. I would be awarded the rank of a[n] "Untersturmfuehrer" (lieutenant) and it were a very definite desire of Himmler that I attend his invitation to join.
    I asked Mueller to give me some time for reflection. He agreed.
    Realizing that the matter was of highly political significance for the relation between the SS and the Army, I called immediately on my military superior, Dr. Dornberger. He informed me that the SS had for a long time been trying to get their "finger in the pie" of the rocket work. I asked him what to do. He replied on the spot that if I wanted to continue our mutual work, I had no alternative but to join./

    That is, everyone who works for his state should be take it position.
    The position of the state is determined by politicians.
    A politician is more often "a liar" who promises one thing, but does something completely different.
    So any inventor depends on "the liar" that tomorrow may be blowing up our planet.
    What can you learn here?
    I dont know. I only know that for any politician the inventor is "a donkey" who will do all that they need if you give him "hay".

    Ok, I dug out the patent. "Fig. 3" is still missing. And the patent still says "Reflector for use in wireless telegraphy and telephony." Marconi patented a 'reflector' not a 'Metamaterial.'

    I can understand your premise that Marconi and Franklin invented 'Metamaterial.' My contention is that they neither realized or understood the implications of their invention as a Metamaterial. What they did was to stumble upon a concept that would not be realized for a century. They invented a reflector that just happened to use capacitance (or inductance according to the patent) to connect a number of shorter elements together - a concept applied to Metamaterials - to form the reflective elements. To say that Marconi and Franklin patented Metamaterials seems a bit of a stretch to me.

    If I were to do a patent search for 'Metamaterial' will Marconi's patent on 'Reflectors' come up in the search?

    Don't get me wrong here. I am not disputing that Marconi and Franklin may have accidentally discovered Metamaterials and/or the concept of Metamaterials. It's the claim that they patented Metamaterials that I disagree with. Perhaps I just don't understand the U.S. Patent (and Patent process).

    I have no interest in convincing you of the facts.

    Metamaterial example from Duke website circa 2012...and Marconi and Franklin patent...see Fig 11. (and original page of diagrams, not just the blow up).

    The patent office--if asked-- would cite Fig 11 as prior art for metamaterials.
