Modeling of Nonuniform Magnetisation of a Ferrite Loaded Waveguide

H. V. Dixit [1], A. R. Jadhav [2], Y. M. Jain [3], A. N. Cheeran [1], V. Gupta [2], P. K. Sharma [3],
[1] Veermata Jijabai Technological Institute, Mumbai, Maharashtra, India
[2] Vidyavardhini's College of Engineering and Technology, Vasai, Maharashtra, India
[3] Institute for Plasma Research, Gandhinagar, Gujarat, India

The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the ... Mehr lesen

Modeling Post Convection Cooling of High Power Waveguide

H. V. Dixit [1], A. R. Jadhav [2], Y. M. Jain [3], A. N. Cheeran [1], V. Gupta [2], P. K. Sharma [3],
[1] Veermata Jijabai Technological Institute, Mumbai, Maharashtra, India
[2] Vidyavardhini's College of Engineering and Technology, Vasai, Maharashtra, India
[3]Institute for Plasma Research, Gandhinagar, Gujarat, India

Waveguide Structures are often used for transmission of high CW power. The inherent conductor losses in the waveguide material lead to an increase in its temperature. If appropriate thermal management is not undertaken, this high temperature may lower the breakdown threshold of the ... Mehr lesen
