“…The electromagnetic field received by a thin-wire probe mounted on the nose of a missile like body of revolution (BOR) has been studied and the signal coupled to the coaxial transmission line has been determined from the far zone field pattern and reciprocity theorem [2]. The application of reciprocity has also been presented for computing, the coupling of a signal, caused by an elementary electric dipole, to a load impedance terminating a coaxial transmission line whose center conductor protrudes into an open-ended cylindrical tube [3].…”

Abstract-In this paper is presented a method for computing, and an experimental procedure for verifying, the coupling of a signal, caused by a modulated laser beam, to a load impedance terminating a coaxial waveguide whose center conductor protrudes into a an open-ended body of revolution (BOR). The excitation is the signal radiated by electrons emitted from the conducting surface by an impinging laser beam, modulated in such a way that the electrons escaping the surface oscillate harmonically in time causing them to radiate a coherent signal at an angular frequency ω. For a vanishingly small spot of laser light on the conducting surface, the radiating source is modeled as an electric dipole normal to and located at the surface. To perform this computation directly is very difficult so we resort to an indirect method that allows us to realize significant savings with no loss in generality. The indirect approach adopted here takes the advantage of the reciprocity and allows one to determine the received signal at the coax terminal load from knowledge of the field radiated by a small wire probe mounted on the symmetry axis of the BOR under the condition that the excitation results from a current generator impressed at the terminal end of the coax. This scheme necessitates the formulation and solution of a simpler integral equation. In principle, the approach developed to solve this problem is exact and rigorous. The validity of this approach is demonstrated numerically and experimentally.

“…Electromagnetic computation for bodies of revolution (BOR) of arbitrary shape has been widely discussed for many years. BOR objects of various types, including perfect electric conductors (PEC), homogeneous dielectric bodies, coated conducting bodies, combined dielectric and conducting bodies, multi-layer dielectric bodies and resonators with axial symmetry, have been studied [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Because of the axis-symmetry of the geometry, only the 2-D cross section that forms the volume (i.e., the meridian plane) is needed for solving the scattering, radiation and resonance problems of the BOR by integral equations (IE) [1][2][3][4][5], finite element method (FEM) [12][13][14], hybrid finite element method and boundary integration (FEM-BI) [15], hybrid physical optics and method of moments (PO-MoM) [16], and the other methods.…”

To analyze resonances in an axisymmetric inhomogeneous cavity, a higher-order finite element method (FEM) is developed. Mixed higher-order node-based and edge-based elements are applied to eigenvalue analysis for the azimuthal component and meridian components of the field, respectively. Compared with the lower-order FEM, the higher-order FEM can improve accuracy with the same number of unknowns and can reduce the CPU time and memory requirement for specified accuracy. Numerical results are given to demonstrate the validity and efficiency of the proposed method.
