Abstract
Radial and longitudinal profiles of the electron paramagnetic resonance (EPR) signal intensity of a point-like sample inserted into a Bruker single TE102 rectangular cavity were computed and the three-dimensional surface plots presented for the set of the point-like samples situated, (i) at any available points, P(rho is an element of <0,b/2>, phi is an element of <0, 2pi>, x is an element of 0), of a circle with a radius, rho(max) = b/2 (5.5 mm), which is located in the horizontal, central (y-z)-plane of the microwave cavity (a radial profile), and (ii) at any available points, P(rho = b/4, phi is an element of <0, 2pi>, x is an element of <-a/2, a/2>), of the cylindrical surface with a radius, rho = b/4, and length, L = a (23.5 mm), which is concentric with the vertical, central x-axis of the microwave cavity (a longitudinal profile). The three-dimensional surface plots of the EPR signal intensity can be used for the theoretical prediction of the experimental response of the microwave cavity to a bulky sample: (i) for movement along (the longitudinal response); and (ii) for rotation around (the radial response) the vertical, central cavity x-axis.
