SCATTERING PARAMETERS OF CIRCULATOR

SCATTERING PARAMETERS OF CIRCULATOR


AIM: To study the operation of ferrite circulator and hence measure
i. Insertion loss ii. Isolation iii. And to determining S parameters

EQUIPMENT: Microwave Source (RKO/GO), Isolator, Variable Attenuator, Frequency meter, Slotted line , Tunable probe with detector, detector mount with detector, VSWR meter, Circulator and Matched Terminations-2.

THEORY: The circulator is a multi port junction that permits transmission ....etc

At present any consignment carried by a vehicle has to travel incommunicado till it reaches the destination. So, both the fleet owner and the persons sending or procuring the consignment have to sit keeping their fingers crossed till the fleet arrives. To track the path of the vehicle and to monitor the various parameters like fuel consumption, kilometers covered and the amount of load in the vehicle an intelligent device would come handy to solve the problem for the fleet operators and the clients. This paper aims at designing an intelligent d ....etc

Wide angle X-ray scattering (WAXS) is an X-ray diffraction technique that is often used to determine the crystalline structure of polymers. This technique refers to the analysis of Bragg Peaks scattered to wide angles, implies that they are caused by sub-nanometer sized structures.Wide angle x-ray scattering is the same technique as Small-Angle X-ray Scattering (SAXS) with the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed.The technique is a time-honored but a somewhat out-of-favor tec ....etc

Abstract-
For near infrared imaging of neonatal head surrounded by cerebrospinal fluid layer, we have developed an imaging modality, which uses perturbation Monte-Carlo estimation of Jacobian of the forward model for photon propagation. In this case, we have shown that the conventional techniques, which uses diffusion approximation for light transport in tissue, fails to give the reconstruction of tissue optical prope ....etc

PERFORMANCE EVALUATION OF OPERATIONAL PARAMETERS ON RFID CONTROLLED CONVEYOR SYSTEM.

ABSTRACT: RFID has been taking great attention of industry for its various advantages. This technology enables to monitor and track items in production facilities, warehouse operations, and distributions. However, RFID system performance is dramatically affected from the operational setting of the system. In particular, identification of appropriate levels for each operational factor is not trivial. In this project, we demonstrate an effective methodology to ....etc

CONDUCTIVITY σ ,FERMI LEVEL ,
MEAN FREE PATH &
RELAXATION TIME ť
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE

The conductivity σ may be obtained experimentally .
Further we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can ....etc
