The presentation is full of inconsistencies,& should be judged in its entirety.
I think the presentation was full or errors, including experimental errors, but I can see no evidence at all that Antony Sutera lied about anything. It is not hard to see how the underwater results could have been wrecked by a very simple error - when he added the spray to the antenna, it turned the radio ground into an antenna by somehow coupling the antenna signal connection to the water (ground), and the transmission was happening in air, not in the water. It looks like the police antenna he touched did get hot (not a lie), the tree antenna could be explained by the fact he could have been comparing a tree dipole to an untuned wideband miniature antenna. He never said what he was comparing it to. The iPhone improvement? Well how did he actually measure the signal strength? Say the iPhone test with the paint was several days after the test without paint, the difference could have been the atmospheric differences at the time. Anthony actually said he was expecting the spray-on tree antenna would have 70% the performance of a commercial antenna, and was surprised how well it appeared to work for him. That is probably a true statement.
I don't think he is a scammer - you just don't pick a market that basically consists of a small number of the biggest organizations with the best labs and the best lawyers with unlimited legal budgets to scam. If you are going to be a scammer, you pick a vulnerable market with huge numbers of victims.
Lets get real - Chamtech is a tiny company with 4 employees and an annual budget reportedly of $320K. They make a spray. They don't make antennas, radios, mobile phones, or any electronic devices that I know of, and almost certainly they don't have the money for a decent RF lab. They probably have almost no income yet, so they are extremely vulnerable.
They are a spray paint manufacturer. I doubt that Anthony has any electronic qualifications, and the company may not have a single RF engineer in those 4 employees.
They make a spray paint that was probably initially designed to DARPA requirements, and they want to get in the door of DARPA (US Military), Apple, Samsung, HTC, Motorola, etc. They probably only have the budget to make a small number of cans, and my suspicion is they actually don't yet have a patent on the spray technology yet. As far as I can see, the only patents they have are some speculative patents of antenna design patterns that I cannot see standing up in court. Basically, the only future the company has is if they have a real product that has useful electrical properties.
The "Solve for X" presentation looked like it was a weekend's work (probably was) and looked like it had all the mistakes that a non-RF engineer could make when trying to test antenna performance on the cheap. It definitely is not the rigorous study we would expect from an engineer, but to me, it matches my expectations for a spray can manufacture trying to test antenna performance. They should do weeks RF anechoic chamber testing to measure the exact properties of the material, but they probably cannot without the resources of a bigger company.
Again I really have to totally bag the technical bloggers - particularly all the ones who turned Anthony vague single test results claims into total fact - that is really, really stupid. Many of the blogger made claims that went beyond anything Anthony actually said.
I just think people are making the mistake of expecting a spray paint manufacturer to behave like a professional electrical engineer with 20 years plus of lab experience. Based on the impressive product at Anthony's previous company (Aero Performance), I am prepared to believe that this is an attempt at a serious product. Whether it is actually useful or not will be decided by a tough and experienced market that I cannot seriously believe will be a victim of any scam. If this presentation manages to get DARPA and companies like Apple to test this spray, then good luck to Chamtech. That is all they seems to be after. I really cannot see them selling this spray on the late night shopping channels along side the ab toning machines. There is just nothing in that presentation that has harmed anyone.
If the spray turns out to have some interesting electromagnetic properties that can be used, then it is a very worthwhile product. Perhaps if screen-printed over the top of a transmission line on a PCB, it changes the transmission line properties? That would be fun to play with.
Chamtech are a tiny company having a go, and I wish them well. "Give'em a Fair Go" as we say here in Oz.
I most certainly don't see it as my duty to protect Apple and the US military from the possibility of being scammed - they don't need my help.
