The Haryana State came into existence on November 1, 1966. The total geographical area of the State is 44,212 sq. km. constituting about 1.3% of the total geographical area of the country . It is now one of the small states of India. It extends between 27039'N to 30055'N latitudes and 74027'E to 77036'E longitudes.. Union territory of Chandigarh forms the capital of the HaryanaState. It is bounded on the north by Punjab State, on the south and southwest by Rajasthan State, on the north-east by Himachal Pradesh, on the south-east by Delhi and the Y amuna River forms a natural boundary in the east separating Uttar Pradesh.Haryana is primarily an alluvial plain. Soils constitute its major natural resource and agriculture is its main-stay . Besides, it shares the Siwalik foothills in the north and Aravalli hills in the south. After its formation, Haryana followed a deliberate policy to take benefit of its proximity to Delhi.

Cylindrical waveguide loaded when helix slow-wave structure (SWS) several distinct modes arises. There would include the fast-wave modes corresponding to the hybrid of the transverse electric (TE) and transverse magnetic (TM) modes arising from the anisotropic conductivity of the helix which internally loads the overall metal envelope ? a conventional cylindrical waveguide. Analysis of helical structure in the first-wave regime with arbitrary azimuthal harmonic modes has been carried out to ensure wideband coalescence between the beam-mode and the waveguide-mode dispersion curves. In this paper , authors have developed an analysis of the structure considering the ef fects of the dielectric-support parameters including the inhomogeneity of the dielectric in a vane loaded cylindrical waveguide.
