ParaScan™ - RF Cafe Cool Product"ParaScan™ is a family of proprietary, composite thin-film ceramic materials whose dielectric constant varies with the application of a DC voltage. Based on a proprietary doped version of Barium Strontium Titanate (BST), ParaScan represents a foundational technology for the ParaTune™ family of tunable ICs . Paratek can produce ParaTune tunable ICs in a virtually limitless number of configurations to meet specific customer needs. Paratek's business model is a flexible one, with customer collaboration representing the cornerstone of this model. The ParaScan material is also exceptionally flexible and can be used in numerous points within wireless components and products to make them better and more efficient! Voltage-tunable ParaScan has exceptional properties, including outstanding linearity and harmonic performance, very low power consumption, and high Q (100 at 1 GHz and more than 80 at 2 GHz). ParaScan also provides high capacitance density, IP3 of greater than 70 dBm, and very fast switching speed."

A Swarm of Nano Quadrotors - RF Cafe Video for EngineersIt is amazing how much of what was merely science fiction a few decades ago is now reality. This video of a swarm of 20 nano quadrotors developed by researchers at the University of Pennsylvania's General Robotics, Automation, Sensing and Perception (GRASP) Lab is reminiscent of something out of Star Wars or The Matrix. Not only are the tiny flying machines autonomously stable, but they can fly in formation either as a fixed shape moving simultaneously from location to location, but they also move in a dynamic formation like marquee lights. Their multiple electric-powered propellers make a high speed droning sound like bees, adding to the ominous presence that a militarized version would present to an aggressor. It's quite cool and quite spooky at the same time. A company called Kmel Robotics is credited with building the nano quadrotors. I want some.

Tesla Towers in Russia - RF Cafe Cool PicIt looks like something from a video game, and in fact, I thought the story was a hoax at first; Photoshopped images are rampant on the Internet. I even verified its existence by doing a Google satellite map on the area just to make sure. Yep, it's real. Here is a massive structure that is reportedly a Tesla generator of some sort. One of the pictures on the AboveTopSecret.com website shows a sign on the gate of the apparently abandoned site that, translated, reads, "Isled. the center of the high energies." There is no information about what the structure was used for, but if you zoom out on the satellite image, you will see to the southeast a round area defined that is about 250 meters in diameter - possibly an underground synchrotron laboratory? Ah, I just found some additional info on it - the footprint of a former giant dome (cupola) that covered an unknown structure. It could have been my guess of a synchrotron, and/or, looking again at the satellite photo, there appears to be some sort or antenna array.

Soaring College Tuition Costs - RF Cafe SmorgasbordSkyrocketing costs for college tuition have been an issue for a long time. Reports published lately show how the price of a semester of college has exploded in the last few decades. Those same investigations have determined that a big part of the increase has been due to the ease at which school loans can be obtained - very similar to the way housing costs have increased with easy access to mortgage money. As students were more able to pay the rate, supply and demand allowed costs to go up accordingly. For instance, the above chart shows that from 1982 to 2007 the cost of tuition, fees, room, and board increased by an average of about 450%. During the same period the median family income increased 150% and the CPI was up 100%. Even medical care "only" increased by 250%. To illustrate the oblivion nature of far too many students, at the behest of professors and administrators who are themselves part of "the 1%," from an income and privilege standpoint, the students attend Occupy Wall Street (OWS) demonstrations to rail against the 1%. Ivory Tower pontificators blasting Capitalism while profiting from it are not limited to universities; their names are in the news on a daily basis.
