INTRODUCTION
The expansion of the world of the „science and technology‟ making drastic change in many aspects.
Nano antenna is an important segment of it. Spherical optical Nano - antenna is designed by a single nano
sphere and dielectric rectangular space. These gold nano sphere and dielectric rectangular space separated
by1nm vacuum space. The vacuum space confined the electromagnetic wave which generates electronic wave
known as wave Plasmon. The performance of this spherical optical nano antenna analyses by mesh analysis of
Electric field ,Magnetic field ,current density and three dimensional RHCP and LHCP polarization pattern for
far field and near field.

ANALYSIS OF THREE DIMENTION POLARIZATION

MEASUREMENT OF THE DIMENSION POLARIZATION PATTERNS FOR NEAR FIELD: Three
dimension polarization pattern of antenna can measure in transmission or received mode. This pattern gives the
measurement of the variation of elevation (θ and φ) with fixed frequency or variation of frequency with fixed
elevation(and φ)) for near field .To achieve the desired pattern cuts for mounting the structure of the system
must have capability to rotate in various planes .This can be accomplished by varying different types of position
as elevation-over -azimuth or azimuth-over- elevation .The three dimension polarization of spherical optical
nano antenna is measured in figure no -1&2 for RHCP and LHCP. This result of three dimension polarization
pattern gives specific polarization pattern cuts that reflects azimuth –over- elevation with sharp slope Swhich
provides capability of spherical nano antenna to rotate in various plane.

MESH ANALYSIS

Mesh analysis is a measurement of the possible large field enhancement of plasmonic resonance. The
enhanced field of spherical optical nano antenna for near to the outer surface and small (1nm) space between
gold sphere and rectangular space of dielectric material of plasmonic optical nano antenna is at the frequency
445THz. The qualitative and quantitative measurement of plasmonic resonance of Electric field, Magnetic field
and current density at frequency 445THz which gives the idea about the performance optical nano antenna and
visualization of its pointing vector field.

II. ANALYSIS OF THREE DIMENTION POLARIZATION MEASUREMENT OF THE DIMENSION POLARIZATION PATTERNS FOR NEAR FIELD: Three dimension polarization pattern of antenna can measure in transmission or received mode. This pattern gives the measurement of the variation of elevation (θ and φ) with fixed frequency or variation of frequency with fixed elevation(and φ)) for near field .To achieve the desired pattern cuts for mounting the structure of the system must have capability to rotate in various planes .This can be accomplished by varying different types of position as elevation-over -azimuth or azimuth-over- elevation .The three dimension polarization of spherical optical nano antenna is measured in figure no -1&2 for RHCP and LHCP. This result of three dimension polarization pattern gives specific polarization pattern cuts that reflects azimuth –over- elevation with sharp slope Swhich provides capability of spherical nano antenna to rotate in various plane. Fig no-1 III. Fig no-2 Three Dimention LHCP Pollarization Patter For Far Field Three dimensions LHCP and RHCP polarization pattern for far field is measured in figure no 3& 4.
