A new approach is presented for dealing with the problem of vibration control in a plate over a moderately wide frequency band. The band of interest does not contain the first few eigenvalues, nor is it restricted to very high frequencies, but typically contains five or six eigenfrequencies in the 1

The vibration and the acoustic radiation of a baffled rectangular plate in contact with a dense fluid is considered. By using Green's representation theorem, the original system of differential equations governing both the displacement and the acoustic sound pressure is transformed into a system of

## Abstract This paper presents a 2D array design composed of rectangular slot antennas tuned with patch stubs. The 2D array of 32 × 32 elements for phased‐array applications achieves a 38‐dB gain, 60% impedance bandwidth, and 65° scanning angle without grating lobes. The return loss, radiation pat
