A Frequency Selective Surface With Miniaturized Elements
We demonstrate a new class of bandpass frequency selective surface (FSS), the building block of which, unlike the traditional FSSs, makes use of resonant dipole and slot structures that haveExpand

MRI-Derived 3-D-Printed Breast Phantom for Microwave Breast Imaging Validation
We propose a 3-D-printed breast phantom for use in preclinical experimental microwave imaging studies. The phantom is derived from an MRI of a human subject; thus, it is anthropomorphic, and itsExpand

A wide-band slot antenna design employing a fictitious short circuit concept
A wide-band slot antenna element is proposed as a building block for designing single- or multi-element wide-band or dual-band slot antennas. It is shown that a properly designed, off-centered,Expand
