In order to full-fill the demand of high performance radome in modern radar antenna systems at millimeter wave frequency regime. The design and analysis of metamaterial based frequency selective surfaces is initiated. In light of this, various metamaterial based novel FSS structures are designed and analyzed based on transmission line transfer matrix (TLTM) method for broadband and multiband radome and RAS applications in microwave as well as millimeter wave frequency regimes.
Equivalent circuit model is used to analyze the FSS unit cell as it gives physical insight into the problem. This method is used to analyze FSS based radome, antennas, and RAS structures.
Major milestones / results of this technique:
Design and analysis of FSS-embedded radome:
Return Loss characteristics of FSS-based antenna
