  By G. Sunil, Selvaraju, T.S. Senthil, N. Saikumari, S. Nooray Sashmi, Sivakumar A., Zakir Hussain, J. Sharmila, Shailendra Kumar Bohidar

  Abstract: Polymer–composite based phase change systems offer an effective strategy for adaptive thermal management; however, most existing systems exhibit single-stage latent heat transitions, limiting their applicability in environments with fluctuating thermal loads. In this study, a thermoplastic polyurethane (TPU) polymer matrix was reinforced with two microencapsulated paraffin-based phase change materials (PCM-A and PCM-B) to achieve multi-level latent heat storage behavior. The fabricated TPU/PCM-A10–B20 polymer–composite demonstrated two distinct endothermic transitions at approximately …

  Study of Effect of Various Dielectrics on the Performance of Electromagnetic Bandgap Based Microstrip Patch Antenna Structure

  By Satish Reddy Kasarla

  Abstract: Here the effect of various dielectrics on the performance of microstrip patch antenna with underlying electromagnetic bandgap structure is investigated. This unique antenna structure suppresses the surface waves and reflects plane waves with no phase change and thus acts as a perfect magnetic conductor (PMC). Dielectric losses are reduced due to the presence of EBG structure and bandwidth enhancement is observed when compared to the non-EBG structure. The effect of …
