A novel kind of circular polarization and dual-frequency linear polarization microstrip antennas is proposed. The designs are based on the anisotropic property of the complementary split ring ...

The development of prodrugs — chemically modified versions of pharmacologically active agents that must undergo transformationin vivoto release the active drug — is a well-established strategy ...

This paper presents a new standard rectangular waveguide bandpass filter (BPF) design method based on complementary split ring resonator (CSRR). 3-dB fractional bandwidth (FBW) from 3.2% to 31% can be ...
