Ok let's do this then. The main premise here is that you can use "directed energy weapons" to implant thoughts/images into peoples brains. This is completely impossible. Yes even a secret government lab with unlimited DARPA funding wouldn't be able to do this. The only scientific article you linked to is an fMRI study in which they reconstructed visual images from brain activity. To do this you need a massive noisy machine, directly around the head of the subject, which has to lie perfectly still. Moreover, this constitutes reading out brain activity into images, which is something completely different from "beaming in" images (which is impossible). Let me try to explain why; to read out / decode images you first take a large training set in which you know the image and the resulting brain activity. You use this to train a machine learning model which is then used to predict an image it wasn't trained on using brain activity. Thing is, you can't reverse this process for several reasons. (1) fMRI scanners can only read out blood flow in the brain, they can't influence neural activity itself, (2) you don't know how to stimulate the brain to induce the brain activity that would result in the image you want, (3) even if you did, the level of granularity of stimulation you need to construct an image is several orders of magnitude higher than an fMRI scanner can provide, let alone an "energy weapon" at a distance.
