Natural Resonances of Slotted Cylinder Configurations
Abstract
Electromagnetic sensitivity of systems from intentional apertures such as radar antennas and optical sensors are generally well studied and understood. Characteristics of electromagnetic energy that leaks into an enclosed volume through unintentional apertures such as seams at bolted, riveted, or screwed joints are not understood analytically or from a practical standpoint. Measurement of the internal electromagnetic field of axially slotted cylinders of varying slot widths provides a simple method for the analysis of internal coupled fields. Experimental results of resonance measurements and theoretical computations conducted on slotted cylinder configurations are presented. These measurements provide practical information on the resonance characteristics of different slotted cylinder configurations. Analysis of the data will provide insight into the phenomena of E-field coupling and natural resonances of slotted cylinders.
