If you use a cellphone you're regularly getting scanned with cm waves. And if you stand in the sun you're getting scanned with nm and um waves. So mm waves are just in between these. And an IC like this should not put out enough power to cause any worse effects on you than any of the above?
I threw up a little in my mouth when I read the following sentence, "... terahertz-range frequencies to safely scan passengers". Please define "safely"? I will never allows someone to scan me with mm waves.
Terahertz images have already obsoleted traditional X-rays for applications where people are involved, from airport full-body scanners to epidermal medical scanners. However, the bulky discrete components required make today's terahertz scanners big, heavy and expensive. If TI can perfect CMOS chip-sized detectors/emitters, then the size, weight and price can he brought down for implementing inexpensive handheld models.
