Abstract In this work, we applied Vilenkin’s additional theorem among the circular apertures to measure the coupling calculations. We measure the vector-Legendre transformations of basis and test functions by keeping the domain over the aperture at an arbitrary level. With the help of Euler’s formula for rotating the coordinate system, we used the classical approach for the numerical measurements, which is... In this work, we applied Vilenkin’s additional theorem among the circular apertures to measure the coupling calculations. We measure the vector-Legendre transformations of basis and test functions by keeping the domain over the aperture at an arbitrary level. With the help of Euler’s formula for rotating the coordinate system, we used the classical approach for the numerical measurements, which is more time intensive. With Vilekin’s additional theorem for Legendre functions, we increased the rotation-based measurements. Read More Read Less

Abstract Using the lumped elements, we have prepared the design of the Chebyshev low pass filter. When the filter with magnitude response is applied, a ladder network with inductor series for shunt capacitors is generated. Initially, we transformed the low pass filter with real lossy reactive elements and then simulated the 3D EM simulator. To experiment with the design created, we... Using the lumped elements, we have prepared the design of the Chebyshev low pass filter. When the filter with magnitude response is applied, a ladder network with inductor series for shunt capacitors is generated. Initially, we transformed the low pass filter with real lossy reactive elements and then simulated the 3D EM simulator. To experiment with the design created, we simulated the filter obtained the values for S-parameters and compared them. In a frequency value of < 200 MHz, the low pass filter is found to have minimal insertion loss. The filter aims to limit the harmonics during high amplifier output. Read More Read Less

Abstract We have outlined the induction motor regulation strategies in this paper. We have presented the methods of speed control for induction motors. The methods have merits and demerits in speed calculation, response need and cost that depend on motor drives. These motor drives are classified into international standards IEC 60034, ranging from S 1 to S 10. This work considered... We have outlined the induction motor regulation strategies in this paper. We have presented the methods of speed control for induction motors. The methods have merits and demerits in speed calculation, response need and cost that depend on motor drives. These motor drives are classified into international standards IEC 60034, ranging from S 1 to S 10. This work considered the last three duty types with speed changes. For some selected duty-type cycles, we made prepositions with speed control. Read More Read Less
