Latest Patents

Penunuri's latest patent, the **Magnetostatic Wave Channelizer**, introduces a magnetostatic wave (MSW) device designed for spectral analysis of input signals with extremely high frequency components, well above 1 GHz. This invention utilizes an input transducer array that effectively couples signals to a magnetostatic propagating medium, such as a film of yttrium-iron-garnet (YIG). The configuration allows for constructive wave combination at frequency-dependent points in the medium, leading to output signals that represent various selected frequency components of the input signal.

His other notable invention, the **Surface Acoustic Wave Systems and Methods**, allows for dynamic modification of the functional properties of a surface acoustic wave (SAW) device. By employing photoconductive material on a wave-propagating substrate and varying light patterns for illumination, this technology alters the interaction between electric fields and waves, enabling enhanced control over sidelobes and scattering within wideband systems. This innovative approach showcases the versatility of photoconductive materials, as they remain unaffected by SAW propagation when not illuminated, but interact significantly under appropriate lighting conditions.
