Person

Langis Roy - Professor

Research

Monolithic integrated Si/GaN/GaAs circuits; high-performance microwave circuit packaging; integrated active antennas; numerical techniques in electromagnetics; optoelectronic packaging; monolithic microwave integrated circuits; low temperature co-fired ceramics; micro-electro-mechanical systems; RF; millimeter-waves.

Application

Wireless electronic devices that can communicate faster than currently available products, yet are smaller, reconfigurable, more efficient and lower-cost. An example is the integration of antennas directly on – or in the same package as – the transmitter and receiver chips, thereby enabling the transmission of high-definition biometric data via a wireless link.
