The effect of 1D photonic crystals on the optical transmission of VO2 is studied by depositing thin films of VO2 nanoparticles on SiO2/TiO2 distributed Bragg reflectors (DBRs) in the near-infrared (IR) spectrum as per the earlier theoretical predictions of Rashidi et al (2018 J. Phys. D: Appl. Phys. 51 375102). Monoclinic VO2 nanoparticles with tuned crystallinity are synthesized using a facile solution processing method. Moderately crystalline (MC) and highly crystalline (HC) VO2 nanostructures are obtained by varying the synthesis temperature and post-growth annealing conditions. Both the MC VO2 and HC VO2 films exhibit the expected reduction in optical transmission in the IR region due to the structural phase transition from monoclinic (insulator) to rutile (metallic) around the critical temperature of 68 °C. By combining VO2 films on a 40% transmitting DBR structure, the average optical transmission decreases further to ~20%. The number of stacks of DBRs plays a key role in such an effective reduction of optical transmission in the IR. When the number of stacks of DBRs is further increased from 4 to 7, the optical transmission of metallic VO2 films on DBRs nearly vanishes in the near-IR spectrum in such vanadium dioxide 1D photonic crystal based composite photonic structures. Such a temperature-controlled, enhanced, broad band optical response could provide a promising design for VO2 nanoparticle based hybrid photonic absorbers for various smart window applications.

<p>This paper consists of an overview and a brief description of all the Beagle Boards from the original Beagle Board released in 2008 to the latest board BeagleV released in 2019. The Beaglebone board is one of the high-end hobby-grade boards and has quite a few applications in industrial/consumer electronics as well. Many beginners prefer Arduino boards and Raspberry Pi boards for tinkering. The Beagle Boards are an amalgamation of both Arduino and Raspberry Pi boards. Owing to their high prices, they are not as widely used as the Arduino boards and Raspberry Pi boards, but the Beagle Boards are robust and have an added advantage in the form of on-board GPU and DSP. Furthermore, the on-chip PRU-ICSS contribute to the computing process increasing the efficiency of the boards. The Beagle boards have multiple OS Support (Debian, LXDE, Ubuntu, etc.). The paper also discusses the interfacing of Beagle boards with various peripherals and components. The various types of capes available for the Beagle boards are discussed as well. The paper also presents an introduction on how to get started with the Beagle boards. The applications of the Beagle boards are discussed as well.</p> <p><br></p>
