A Compact Coupled Band-Pass Frequency Selective Surface for Examination of Human Body Part Using Ultrasonography

A compact coupled band-pass frequency selective surface (FSS) for medical use is submitted in this paper. The ultrasonography uses a frequency of 3MHz and 5MHz for examination of abdominal part and neck part respectively. The presented model is simulated using CST MWS electromagnetic simulation software. Square loop structure is out forwarded. The current distribution for the two-resonance frequency is analysed well. Output is accurate enough for both transmission and reflection coefficient in both TE and TM mode. Angular stability up to 60° is achieved.
