Broadband Radar Invisibility with Time-Dependent Metasurfaces
In the modern aerospace and defense sectors, stealth technology is crucial for aircraft survivability. Current methods primarily rely on shaping, radar-absorbing coatings, and electronic jamming to evade detection. However, these techniques face substantial limitations: they are often narrowband, bulky, and vulnerable to sophisticated radar systems that can distinguish stealth aircraft, especially when targets are moving.

Energy Harvesting Module and Low Power Rectifier Circuit
RADIO frequency (RF) energy harvesting has garnered much interest in recent years as our lives have become more connected. Whether it be smart homes, industry 4.0, wearables or sport-tech; objects which were once inanimate are brought to life with electronics such as sensors, and low-power transceivers. This evolution of ‘things’ is commonly referred to as […] Read More >
Sensitive Electrochemical Detection of Soybean Rust Fungi Airborne Urediniospores
The agricultural sector faces significant challenges due to plant diseases, which can lead to substantial economic losses. Among these diseases, soybean rust, caused by the fungus Phakopsora pachyrhizi, poses a severe threat to soybean crops worldwide. Early detection of airborne urediniospores is crucial for effective disease management and prevention strategies. Traditional detection methods often lack […] Read More >
Caches With Many Ways: 16-way Associativity for the Price of 2-way Associativity
Cache design must meet many conflicting demands: high hit rates, low cost, low power, low latency and high throughput. We propose a novel cache design for 16-way associativity with cost and power consumption like 2-way associativity. UNMET NEED We propose a novel cache design with the following features: • High effective cache capacity • Misses […] Read More >
Hardware Accelerators for Data Structures
We present the first parallel architecture for a dynamic data-structure for approximate membership (i.e., a filter). The dynamic filter supports insertions, deletions, and approximate membership queries. Our architecture borrows techniques from PRAM emulation to parallelize filters based on two levels of fingerprints. A key component in the architecture is a special-purpose wide-word processor we designed […] Read More >
A novel method to remotely detect plant sound emission, as a response to induced stress
A novel system developed to remotely detect plant sound emission, as a response to stress. The system consists of hardware and software components: microphones that remotely pick up the plant’s sounds in the ultrasonic range of 20 to 100 kilohertz; a signal processing layer; and a machine-learning algorithm that classifies the recorded sounds and reports […] Read More >
Hardware Accelerators for Data Structures
We developed the first parallel architecture for a dynamic data-structure for approximate membership (i.e., a Bloom filter that also supports deletions). UNMET NEED The filter architecture supports multiple operations per cycle while preserving sequential order with a fixed and stable throughput that does not depend on the type of operations, the workload, or how populated […] Read More >
An On-Chip Sub-THz Scalable Beam Steering Antenna Array
We present a novel way of distributing signal to an antenna array without the use of power dividers. In our proposed method, we use the leaked fundamental from a non-linear harmonic generator circuit as an input to drive the next element in the chain. As a proof of concept, we show this distribution method at […] Read More >
Broad-Bandwidth, Long-Haul, Underwater Fiber-Optic Sensing System
An optical fiber can be described as a glass pipeline which can guide light over great distances with very little loss. In addition to being the central communication channel of the information era, it has another very interesting application. This application is called distributed sensing. By launching into the fiber specially designed pulse sequences of […] Read More >
