Optimization of transmitted power of horn antenna for biomedical applications

Lung cancer is considered the deadliest type of cancer for humans and is often diagnosed at the incurable stage. Till now, no effective methods for early diagnosis and treatment of lung cancer have been developed. This short paper presents preliminary studies on millimeter-wave (MMW) effect on yeast cells. It is well known that yeasts are representative of human cells, in many aspects of fundamental cellular processes. Initially, transmitted power from the horn antenna is optimized for both near-field and far-field regions. The studies were performed for the W-band of MMWs (75-110 GHz). Preliminary studies suggested that the MMW radiations with a maximum incident power density do not alter the number of colonies of yeast cells.
