is called the radiation intensity U (watts per steradian or per square degree). The radiation intensity is independent of distance. 4. Define Beam efficiency? The total beam area ( ΩA) consists of the main beam area ( ΩM ) plus the minor lobe area ( Ωm) . Thus ΩA = ΩM+ Ωm . The ratio of the main beam area to the total beam area is called beam efficiency. Beam efficiency = ΣM = ΩM / ΩA. 5.Define Directivity? The directivity of an antenna is equal to the ratio of the maximum power density P(θ‚φ)max

ABSTRACT OF LCOS DISPLAY Modern display technology has made it generally easier and cheaper to create complex visual stimuli than was possible with the older optical systems. However‚ all of the display types in widespread use have significant limitations. Common CRT displays are inexpensive‚ have reasonably good spatial and temporal resolution‚ and reasonably high contrast‚ but are dim. LCD projectors are brighter‚ but suffer from low contrast. One-chip micromirror (DLP) devices that temporally

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which
