Approximation of the Field Components of TE and TM Modes in Waveguides and Cavities with General Cross Section
This paper shows that the field components of TE and TM modes of waveguides and cavities with general cross section can be approximated by a power series consisting of a separeble solution and nonseparable solutions of Helmholtz wave equation corresponding to the rectangular waveguide.
Non-separable solutions of Helmholtz' equation revisited
Even if the idea is already very old (proposed first by Moseley in 1965), it offers analytical solutions of Helmholtz equations for curved waveguides. One of the key elements in their successful use is the computation of recursion formulas to find a numerical solution to the problem of analysis of generally shaped waveguides. They will be derived in this paper. Even if the original theory includes a generalisation to 3 dimensional cavities we will limit ourselves to 2 dimensional waveguide cases.
The need of relationship marketing in higher education
This paper is about research conducted in order to find the graduates’ perceptions regarding their opportunities to find a job after the 1 cycle of study. The main aim was to find their intentions to look for a job in the study field and how they perceive the easiness to find such a job. The outcomes have revealed that the respondents want a job in the study field, but they are anxious about a good integration on the labour market. In this respect, the higher education institutions have to communicate better with their students and other stakeholders in order to implement the relationship marketing in the organisation.
