Abstract

To analysis field strength and protect sensitive circuits in shielding cavity, Field enhancement effect has been researched in frequency domain with shielding effectiveness by using electromagnetic simulation software CST. Experimental system has built with a vector network analyzer, power amplifier, GTEM cell and pulsed electromagnetic field measuring probe to verify the simulation results. Theoretical analysis about the formation mechanism of the field enhancement effect is studied, influence of shape of aperture, electromagnetic wave polarization direction, absorbing material loaded on field enhancement effect are also researched.
