Core-Shell Nanomagnets: Out with Rare-Earth Metals
The Problem:
Many of the permanent magnets currently being made are made of rare-earth metals. These metals have operational temperatures below 150°C. This is problematic for motor applications (i.e., electric motors) that require operational temperatures of at least 160°C, and leads to a loss in the magnetic properties of the metals. Further,...

Vehicle Communication: Low-Profile Dual-Frequency Antenna
The Problem:
To prevent traffic accidents, U.S Department of Transportation plans to enforce future automobiles to incorporate dedicated short-range communication devices (DSRC), which accommodates vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. To date, there has not been an antenna small or efficient enough to transmit...

Reducing the Extra Noise: Patch Antennas with Ferrite Cores
The Problem:
Microstrip patch antennas are widely used in advanced wireless communication systems, however, they suffer from excess harmonic radiation. During the transmission of information between antennas (such as a phone call), noise from other parts of the system is captured. This “noise” then affects the quality of the information...

Compact, High-Performance Mobile Device Antenna
The Problem:
Antenna material plays an important role in antenna performance, and is an ongoing area of research. Ferrite antennas have found limited use in the wireless application areas of interest, primarily because of their poor radiation efficiency, propensity to thermal damage due to overheating, and their poor frequency response at high carrier...

Method for Radio Direction Finding and Channel Sounding
The Problem:
Radio direction finding is a technique used to determine the angle of arrival (AoA) of an incoming radio-frequency wave signal to understand the propagation environment in urban and suburban settings. The AoA estimation is widely utilized in emergency services, geolocation of cell phones, amateur HAM radios, and will serve in connecting...

Spiral Antenna with Perturbation Elements
The Problem:
Current antennas on the market allow for either circular polarization or wide bandwidth range, but not both. Also, if the technologies available today were combined the resulting antenna would be too large for its intended applications in auto, aviation and telecommunications. CubeSat antenna development specifically faces several challenges,...

Integrated Magnetic Inductors
The Problem:
Current magnetic inductor technology utilizes the single phase, hard or soft, ferromagnetic materials or an air-core. They both have difficulty in achieving high permeability and ferromagnetic resonance frequency, because the soft phase has a higher saturation magnetization and smaller magnetic anisotropy field than the hard phase. Furthermore,...
